To check for interference
1 Use
AMACTIVATE to activate the SUBPULLY subassembly.
Context Menu In the graphics area, right-click and choose Assembly ➤
Activate Assembly.
Specify the SUBPULLY subassembly.
2 Use
AMINTERFERE to check for interference.
Context Menu In the graphics area, right-click and choose Analysis ➤
Check Interference.
3 Specify DPULLEY3. No interference should be detected.
Assigning Mass Properties
Next, calculate mass property information. You can analyze parts and assem-
blies during the course of designing. You may need to optimize weight, max-
imize stiffness, balance loads, ease assembly, or meet particular requirements.
One mass properties dialog box contains both Setup and Results tabs that
function the same for both parts and assemblies. In this case, the parts list in
the dialog box displays all parts and part properties in the activated assembly
to be analyzed. Item numbers are also displayed if a BOM exists. When you
select an item in the parts list, it is graphically highlighted on the screen.
In these steps, you analyze the bracket and change tolerance values and
material types.
To set up mass properties
1 Activate the PULLYASM assembly.
Context Menu In the graphics area, right-click and choose Assembly ➤
Activate Assembly.
2 Use
AMMASSPROP to analyze the mass properties of the assembly, responding
to the prompt.
Context Menu In the graphics area, right-click and choose Analysis ➤
Mass Properties.
Select parts or subassemblies: Select the bracket, and press
ENTER
The Assembly Mass Properties dialog box is displayed with the Setup tab
active. In the Materials Available window, the materials listed are all of those
defined in the active assembly.
