Click the Run button at the bottom of the dialog to run morphogenesis. 5. The Morphogenesis Run Status window appears. You can monitor the progress of each run in the window. A run name is a concatenation of the name under Name of run and the percent of the design space being used for the shape in that run. The number in parentheses is a counter that increments each time you make a new run. 6. The runs should be complete in a minute or two. When runs complete successfully, their progress indicators are replaced by green circles as shown below. 8

7. When all three runs have finished, double-click the run named bridge 15% (1). The generated shape appears in the modeling window. 8. Double-click the shape and the mini toolbar for the shape appears in the top right corner of the modeling window. Explore the shapes 1. Click near the tic mark at the 20% position on the Percent of Design Space scale. The shape is changed to show the result of the 20% run. Click each of the 3 tic marks to compare the shapes generated by the three runs. 9

2. Click in the grid to modify the amount of material and detail in the current shape. You can change the amount of material and detail independently of one another by clicking on the scales outside the grid. 3.

Run morphogenesis to generate shapes 1. Select the Run Morphogenesis icon in the main toolbar. 2. The Run Morphogenesis window appears. 15

3. Under Percent of design space to keep, enter 20. This will generate one shape using 20% of the material in the design space. 4. Click the Run button at the bottom of the dialog to run morphogenesis. 5. The Morphogenesis Run Status window appears. You can monitor the progress of the run in the window. A run name is a concatenation of the name under Name of run and the percent of the design space being used for the shape in that run. The number in parentheses is a counter that increments each time you make a new run. 6. The run should be complete in three or four minutes. When runs complete successfully, their progress indicators are replaced by green circles as shown below and green flag appears above the Run Morphogenesis icon. 7. When the run has finished, double-click the run named desk 20% (1) or click the green flag at the top of the run Run Morphogenesis icon. The generated shape appears in the modeling window. 8. Double-click the shape and the mini toolbar for the shape appears in the top right corner of the 16

modeling window. 9. Rotate the view with the mouse to study the generated shape. Explore the shape 1. The single tic mark at the 20% position on the Percent of Design Space scale denotes the single morphogenesis run. 2. Click in the grid to modify the amount of material and detail in the current shape. You can change the amount of material and detail independently of one another by clicking on the scales outside the grid. Explore a variety of shapes by clicking above and below the center of the grid. The center of the grid represents the nominal solution proposed by morphogenesis. 17

3. To see the original part, click the Show Design Space icon,, at the top of the mini toolbar. The original part and environment are shown in the modeling window and the shape controls are removed from the mini toolbar. The Show Design Space icon is replaced by the Show Previous Shape icon,. 4. To see the shape you were previously viewing, click the Show Previous Shape icon,, at the top of the mini toolbar. The generated shape is shown and the mini toolbar is extended to show the shape controls again. 5. You can also click in the drop-down list to select between the original design and the generated shape. As you make more runs on this part, each additional run will appear in the drop-down list. 7. Return to the original design space by clicking the Switch to Design Space icon, the mini toolbar. The design space and environment are displayed., at the top of Create additional environments In this section we add more forces to the desk and group them into different environments. 18

Environments are used to organize forces into groups that act at different times on the model. We will then re-run morphogenesis using all of the new environments we've defined. 1. Double-click the force on the top of the desk. This activates the force-creation mode. Doubleclicking an object is a convenient short-cut for editing and creating more of the same type of object. 2. Move the mouse cursor to the edge of the top of the desk and apply 4 more 500 lbf forces in the directions shown below. By applying the forces to the top edge around the perimeter of the top, the force is evenly distributed across the perimeter. The location of the force along the edge is not important since the force is distributed across the entire edge anyway. In the picture below, the forces have been spread around the perimeter for clarity. 3. Click the List Environments... tool in the environment icon. The Environments window appears. 19

4. Click on Environment 1. Checks appear to the left of each force and support to indicate that each one is currently included in the default environment, Environment 1. 5. If we ran morphogenesis again right now, the 4 side forces would cancel each other out since there are two equal and opposing forces in the X direction and also in the Y direction. We can specify that each force acts at a different point in time from the other forces by separating them into different environments. Morphogenesis generates a shape that satisfies any number of different environments by evaluating the shape against each one independently. 6. We will now create 4 more environments and then include one newly created side force into each of these four environments along with the support in each environment. 7. Click the "+" icon above the Environments column 4 times to create 4 new empty environments. 8. Click on Environment 1 and then activate the checks next to Support 1 and Force 1. Disable all the other checks. To help you remember which force is which, you can rename them in the table as shown below. Don't worry if the order of your forces is different than what is shown here. The forces are simply listed in the order you create them. 9. Click on Environment 2 and then activate the checks next to Support 1 and one of the side loads. Disable all the other checks. 10.Repeat the step above, placing Support 1 and each of the remaining 3 side loads into environments 3, 4 and 5. The environments should be configured as shown in the following table 20

when you are done. It's ok if your environments are organized differently as long as the 5 forces are distributed among the 5 environments and each environment contains the support. Environment 1 Environment 2 Environment 3 Environment 4 ü Side load +x ü Side load +y ü Side load -x ü Side load -y Support 1 Top load Environment 5 ü ü ü ü ü ü Re-run morphogenesis using multiple environments 1. Select the Run Morphogenesis icon in the main toolbar. 2. The Run Morphogenesis window appears. The 5 environments appear in the environment list in the window. A check should appear next to each environment, indicating which environments will be used in the next run. 3. Click the Run button. 4. When the run has finished, double-click the run named desk 20% (2) or click the green flag at the 21

top of the Run Morphogenesis icon. The generated shape appears in the modeling window. 5. Double-click the shape. The mini toolbar for the shape appears in the top right corner of the modeling window. 6. Rotate the view with the mouse to study the generated shape. 7. The result is quite different from the original run. The new shape is capable of withstanding the variety of side loads and the legs have been merged into a continuous "skirt". 7. You can compare run (1) and run (2) by clicking the two run names in the mini toolbar on the right. 8. Return to the original design space by clicking the Switch to Design Space icon,, at the top of the mini toolbar. The design space and environment are displayed. Generate discrete legs using point supports You can create a shape that has four legs by modifying the supports on the bottom of the desk. In the run above, by using a surface support on the bottom of the desk, morphogenesis was free to use whatever portions of the bottom surface it needed to create legs. You can generate a shape with four discrete legs by using four individual point supports on the bottom placed at the locations where you want feet to touch the ground. 1. Double-click the support on the bottom of the desk. This activates the support-creation mode. Recall that double-clicking an object is a convenient short-cut for editing and creating more of the 22

same type of object. 2. While holding down the Shift key on the keyboard, click four positions on the bottom surface of the desk. Pressing the Shift key while creating supports creates point supports rather than surface supports. 3. The four new supports you just created were all placed in the current environment. You need to include each of the point supports in each environment and remove the old surface support from each environment. You could do this using the Environments list in the same manner we used to include the forces in the environments but we'll use another convenient method instead. 4. Select any one support. 5. Select all supports by pressing Command+a on the keyboard. Command+a is a shortcut for selecting all objects that are similar to the currently selected object. 6. Right-click any of the selected supports to activate the context menu. 7. Choose Include in Environments > from the context menu and place a check next to each environment as shown below. 23

8. Dismiss the menu by clicking anywhere outside of the menu. 9. Right-click the original surface support and use the Include in Environments > menu to remove it from each of the environments. 10.Run morphogenesis again by clicking the Run Morphogenesis icon,, and then pressing the Run button. 11.When the run has finished, double-click the run named desk 20% (3) or click the green flag at the top of the run Run Morphogenesis icon. The generated shape appears in the modeling window. 12.Double-click the shape. The mini toolbar for the shape appears in the top right corner of the modeling window. 13.Rotate the view with the mouse to study the generated shape. 24

14. You can compare run (1) and run (2) and run (3) by clicking the three run names in the mini toolbar on the right. 15. Return to the original design space by clicking the Switch to Design Space icon,, at the top of the mini toolbar. The design space and environment are displayed. Generate vertically extruded legs by applying a parting direction You can create an "extruded" shape for the legs by applying a parting direction to the design space. If you intend for the desk to be manufactured by molding it in a two-part mold, it must have a shape which allows the two halves of the mold to separate after the part is formed. 1. Click the Parting Directions tool on the Shape Controls icon. The cursor appears as 2. Click the desk. A large gold arrow appears pointing toward the top of the desk. The parting arrow indicates the direction a "mold" will be pulled away from the part. 3. Click the Z icon on the mini toolbar to reverse the direction of the arrow. The arrow points toward the feet of the desk, indicating the legs should taper toward the bottom. 25

4. There's no need to change any environments. A shape control is not included in an environment; it specifies a requirement for the shape of the part regardless of what environments the part is subjected to. 5. Run morphogenesis again by clicking the Run Morphogenesis icon,, and then pressing the Run button. 6. When the run has finished, double-click the run named desk 20% (4) or click the green flag at the top of the run Run Morphogenesis icon. The generated shape appears in the modeling window. 7. Double-click the shape. The mini toolbar for the shape appears in the top right corner of the modeling window. 8. Rotate the view with the mouse to study the generated shape. 26

9. Observe that the leg structures are now extrusions that taper toward the bottom. 10.You can compare runs (1) - (4) by clicking the run names in the mini toolbar on the right. 11.Return to the original design space by clicking the Switch to Design Space icon,, at the top of the mini toolbar. The design space and environment are displayed. Generate laterally extruded legs with a split parting direction You can change the orientation of the parting direction and use a "split" part to form yet another design variation. 1. Double-click the parting direction arrow to activate its' mini toolbar. 2. Click the X icon on the mini toolbar to orient the parting direction arrow laterally across the desk. 3. Click the top left icon on the mini toolbar and choose Split Parting Direction. The parting arrow is now a double arrow, indicating that the resulting shape will be formed as though two mold halves were pulled apart from somewhere in the middle of the part. 27

4. Observe that the parting arrow is oriented laterally across the desk. Let's rotate it slightly around the Z axis to make it align better with the desk. 5. Orient the view with the middle mouse button so that you see the bottom of the desk straight on. Alternatively, you can jump to the bottom view by clicking near the bottom of the View icon: 6. Click the Rotate Parting Direction icon,, on the mini toolbar. The Rotate tool appears at the center of the parting direction. 7. Move the mouse cursor over the rotational arrow on the rotate tool as shown below. Note that the cursor changes to a as you pass over the arrow. 28

14.Observe that the leg structures are now extrusions that taper laterally across the width of the desk. 15.You can compare runs (1) - (5) by clicking the run names in the mini toolbar on the right. 16.Return to the original design space by clicking the Switch to Design Space icon,, at the top of the mini toolbar. The design space and environment are displayed. Create symmetric legs You can enforce symmetry in your desk legs using Symmetry Planes. You can apply up to 3 planes of symmetry across your design space to produce more symmetric shapes even when the environments or design space are not symmetric. 1. Remove the parting direction shape control by right-clicking it and choosing Delete from the context menu. (You don't actually have to delete the parting direction if you don't want to, but you will get a more interesting shape in this stage of the exercise if you do.) 2. Right-click the desk design space and choose Shape Controls > Symmetry Planes from the context menu. Three red planes appear through the desk. The planes are orthogonal to one another. 30

3. Left-click once on the plane which is parallel to the top and bottom surface of the desk to deactivate it. A deactivated plane is drawn with dotted grey edges. Clicking repeatedly on an individual symmetry plane activates and deactivates it. 4. Leave the other two planes active. 5. View the desk from the bottom by rotating the view with the middle mouse button or by clicking the bottom view on the view icon. 6. Click the Rotate Symmetry Planes icon,, on the mini toolbar.

In Inspired, click the Apply Supports tool in the environment icon in the main toolbar. 2. Rotate the view by dragging the mouse with the right mouse button. Orient the view so you can see the bottom surface of the bookcase. 3. Move the mouse cursor over the bottom surface until the cursor hint displays a face support, Zoom into the bottom surface by scrolling the mouse wheel toward you or by dragging the mouse up and down with the right mouse button while holding down the Alt key. 4. Left-click to apply the support. A support is drawn as a cluster of red cones and appears at the point you select, but will support the entire bottom surface. This constrains the bottom of your bookcase so it won't move. Your model should look like the picture below: 36

Apply forces 1. Select the Apply Forces tool in the environment icon in the main toolbar. 2. Rotate the view to expose the shelves of the bookcase. 3. Move the mouse cursor over each shelf and apply a force of 100 Newtons, in the -Z direction, to each shelf by left-clicking on the surface. A force is created and the mini toolbar for the force appears. A force of 100 Newtons is approximately 20 lbs. See Numbers and Units for more information regarding the entry of values and unit conversion. 4. While remaining in force creation mode, move the mouse cursor over the top of the bookshelf and left-click the top surface. This will generate another force with the same magnitude and direction at the top of the bookcase. After creating these forces, each shelf and the top of the bookcase should have a force of 100N applied to it. 37

Run morphogenesis to generate shapes 1. Select the Run Morphogenesis icon in the main toolbar. 2. The Run Morphogenesis window appears. 38

3. Under Percent of design space to keep, enter 10. This will generate one shape using 10% of the material in the design space. 4. Click the Run button at the bottom of the dialog to run morphogenesis. 5. The Morphogenesis Run Status window appears. You can monitor the progress of the run in the window. A run name is a concatenation of the name under Name of run and the percent of the design space being used for the shape in that run. The number in parentheses is a counter that increments each time you make a new run. 6. The run should be complete in three or four minutes. When runs complete successfully, their progress indicators are replaced by green circles as shown below. 39

7. When the run has finished, double-click the run named Bookcase 10% (1). The generated shape appears in the modeling window. 8.
