2 Agenda Bodies When to Sync Reverse Engineering Surfaces Hybrid Surfacing Synchronous Copies Patterns Page 2

3 Import and Use Body Control Page 3

4 Bodies Bodies are supported in 3 States Design Bodies Construction Bodies Stored Bodies Nature Contains Matter in different states Water Analog for simplicity No need for Plasma or Super Strings Water state changes are not cyclical Page 4

5 Water in Nature Missing Processes Gas evaporate condense Solid Liquid Page 5 thaw freeze

6 Design Bodies Basic Solid Modeling element Solid State of Matter Closed Volume Solid Base Feature Single Body Imported Disjoint Bodies allowed Honored in Drafting Multiple Design Bodies allowed (since ST5) Solid Page 6

7 Construction Bodies Construction Elements adapt Liquid State of Matter More Diverse types than Design Open or Closed Volumes Multiple Solid Bodies on Import Not Honored in Draft Single Face or Groups of Faces Synchronous Detached Bodies Liquid Page 7

8 Bodies in Storage Bodies are always represented in the PathFinder Gas State of Matter Stored data in the model Has Mass adds to file size Shows Display state Body State Number of Bodies Composition of Bodies Gas References Hidden Bodies Bodies are also allowed on Clipboard Cut or Copied Features, Faces, and Bodies Dimensions and Relationships Pasted elements Page 8 Detached Sync Faces Live Sections Used Sketches Relationships Feature Profiles Suppressed Features Rolled Back (go to)

11 Bodies change States Commands alter Body States Each body State has a path to another state Design Bodies Design to Construction (Toggle, Detach) Design to Stored (Copy, Cut, Suppress) Construction Bodies Construction to Stored (Hide, Copy, Cut, Suppress) Construction to Design (Toggle, Attach) Stored Bodies Stored to Construction (Show, Paste, Unsuppress) Stored to Design (Show, Paste, Unsuppress) Page 11

12 Body State Change Usage Design Body Construction Clipboard Construction - Design Page 12

13 Import and Use Reverse Engineered Surfaces Page 13

14 Organic Shapes and Forms When Curves Matter Some models have never been digitized Organic shapes askew Historically necessary Not everything is a simple primitive Ordered works best, Sync also has solutions. Page 14

15 Stealing Beauty Start with an Image Hand drawn, Photograph, or previous model Orthographic Views (Side, Top, Front, Right) Account for lens perspective in Photographs Use large input images Pay attention to shadows and highlights Crop to extents of form Insert as image into sketches Page 15

16 Scaling and Size Get the hard points Research and measure original Add a sketch Insert the Image Lamborghini LP400 Specs Wheelbase 2450 mm / in Overall length 4140 mm / in Overall width 1890 mm / in Overall height 1070 mm / in Front track 1500 mm / in Rear track 1520 mm / in Ground clear. 125 mm / 4.91 in Front overhang 933 mm / in Rear overhang 757 mm / in Page 16

17 Scaling and Size Get the hard points Align sketch elements to image Dimension to Specification Lamborghini LP400 Specs Wheelbase 2450 mm / in Overall length 4140 mm / in Overall width 1890 mm / in Overall height 1070 mm / in Front track 1500 mm / in Rear track 1520 mm / in Ground clear. 125 mm / 4.91 in Front overhang 933 mm / in Rear overhang 757 mm / in Page 17

18 Scaling and Size Get the hard points Research and measure original Scale the form Dimension and Place sketch elements Align sketch elements to image Perform same on all projections. Lamborghini LP400 Specs Wheelbase 2450 mm / in Overall length 4140 mm / in Overall width 1890 mm / in Overall height 1070 mm / in Front track 1500 mm / in Rear track 1520 mm / in Ground clear. 125 mm / 4.91 in Front overhang 933 mm / in Rear overhang 757 mm / in Page 18

19 Scaling and Size Get the hard points Research and measure original Scale the form Dimension and Place sketch elements Align sketch elements to image Perform same on all projections. Page 19

20 Find the Form Start with what you Know Identify the clear parts of the form Add Profile sketch on top of image sketch Align Profile sketch elements to image Use 2D Curves to form Add Profile Sketches for all Projections Page 20

21 Find the Width Model half, Mirror later If symmetrical, then model one half Surfaces not actually required Extrude beyond the image Page 21

22 Sweep and Split Sweeping a Surface Sweep path defined by top view Sweep Profile defined by Front / Rear views Page 22

23 Sweep and Split Integrating Surface elements Split Design Body with Surface Boolean to keep both bodies (optional) Page 23

24 Top Dead Center Crowning Achievement Most production surfaces are cast or pressed Think about how it got made Always be flat at mold seam center of model for most symmetric designs Maintain Tangency of sketches with Relationships Page 24

25 Building and Stitching Contain Volumes with Surfaces Extrude surfaces from the known flat areas in sketches Create Bounded or Blue Surfaces for Unknown areas Toggle to Construction / Design Trim to common area Stitch into Solid Body Page 25

26 Optical Illusion Reflective Plane Display Use half the model to see the entire volume Virtual Mirror with no Mass No Selection is allowed Active view Page 26
