Introduction Creating a simple Assembly
Goals: - use advanced sketch and 3D tools
- become familiar with assembly
Guiding thread case: - start from scratch to a simple assembly
-
2012 ANSYS, Inc. June 4, 2014 31
Introduction Creating a simple Assembly Options
To begin we will change some options. Go to the File menu in the top left corner of the screen. Once there select SpaceClaim options
at the bottom
Then go to the advanced tab and make sure that Auto-extrude is on. These will allow you to create solids in section mode and power select quicker.
Go to the units tab and make sure you are in Metric.
-
