2 3D Modeling Steps - Sketch Step 1 Sketch Geometry

3 Sketch Geometry Line Sketch Tool

4 3D Modeling Steps - Constrain Step 1 Sketch Geometry Step 2 Constrain Geometry A. Apply Geometric Constraints

5 Geometric Constraints Applied First Geometric Constraint Tools What do you think we do next?

6 3D Modeling Steps - Constrain Step 1 Sketch Geometry Step 2 Constrain Geometry A. Apply Geometric Constraints B. Apply Dimension Constraints

7 Dimension Constraints Applied Second Dimension Constraint Tool

8 The geometry that has been constrained is a profile of an object.

9 3D Modeling Steps - Extrude Step 1 Sketch Geometry Step 2 Constrain Geometry A. Apply Geometric Constraints B. Apply Dimension Constraints Step 3 Extrude the Object from the Profile A. Change View to Isometric (Home)

10 Profile Changed to Isometric Right mouse click, select Home View or use shortcut key F6 or Click on Home icon by View Cube

11 3D Modeling Steps - Extrude Step 1 Sketch Geometry Step 2 Constrain Geometry A. Apply Geometric Constraints B. Apply Dimension Constraints Step 3 Extrude the Object from the Profile A. Change View to Isometric (Home) B. Switch to Features Environment

12 Features Environment Select Finish Sketch to switch to Features Environment From this view To this view

18 Summary Steps in Parametric Modeling Step 1 Step 2 Step 3 Sketch Constrain Geometry Extrude

19 Parametric Modeling Part 2

20 Adding a Feature to a Solid Model Step 1 Add Sketch Plane to surface on which geometry will be sketched

21 Create New Sketch Plane Sketch Button Sketch plane selected with left mouse click

22 Steps for Adding a Feature Step 1 Add Sketch Plane Step 2 Sketch Geometry

23 Sketch Geometry Add line to Front face Normal View selected with View Face tool or by clicking on front of View Cube

24 Steps for Adding a Feature Step 1 Add Sketch Plane Step 2 Sketch Geometry Step 3 Constrain Geometry

25 Constrain Geometry

26 Steps for Adding a Feature Step 1 Add Sketch Plane Step 2 Sketch Geometry Step 3 Constrain Geometry Step 4 Create Feature

27 Feature Parameters Set Choose cut operation here Isometric (Home) view selected, Extrusion dialog box set

28 Feature Created

29 Summary Adding a Feature to a Solid Model Step 1 Step 2 Step 3 Step 4 Create Sketch Plane Sketch Geometry Constrain Create Feature

30 Let s see it again this time we will create a hole feature.

31 Rotate Model View Cube Dynamic Rotation Rotate model with Dynamic Rotation tool or View Cube

32 Step 1 Create New Sketch Plane

33 Step 2 Sketch Geometry This tool used to create center point geometry

34 Step 3 Constrain

35 Step 4 Create Hole Feature Hole Feature selected from Modify panel on 3D Model tab

36 Completed Hole Feature

37 Model with Hole Feature Hidden Edge Display Model in Isometric view with hidden edges displayed

38 Summary Adding a Feature to a Solid Model Step 1 Step 2 Step 3 Step 4 Create Sketch Plane Sketch Geometry Constrain Create Feature

39 Why Parametric Modeling? Determine the shape and size of the geometry at any time during the design process. This part should be 5 in. long, not 3 in. How can we fix this without redrawing it?

40 Why Parametric Modeling? Benefits Shape before size Geometric and dimension constraints used to capture design intent All files can be quickly updated Existing data can be used for new designs Quick design turn around
