1 Parametric Modeling

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 To this

13 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 C. Preview the Extrusion

14 Extrusion Parameters Set Extrusion Dialogue Box Select Extrude from Create panel

15 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 C. Preview the Extrusion D. Apply Extrusion

16 Profile Extruded Choose color here

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

18 Part 2 Parametric Modeling

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

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

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

22 View Face Sketch Geometry Normal View selected with View Face tool or by clicking on front of View Cube

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

24 Constrain Geometry

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

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

27 Feature Created

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

29 Lets see it again … …this time we will create a hole feature.

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

31 Step 1 Create New Sketch Plane

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

33 Step 3 Constrain

34 Step 4 Create Hole Feature Hole Feature selected from Modify panel

35 Completed Hole Feature

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

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

38 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?

39 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
