Setting Mass Properties in Layout Sketch Blocks

With SolidWorks Motion added in, you can modify the mass properties for each layout sketch block used in a Motion Analysis motion study.

1. Open the layout sketch for an assembly and click Layout (Layout Tools toolbar).
2. Select a layout sketch block entity.

   The Block PropertyManager appears with an estimated value for the block mass under Mass Properties.

3. Modify the Mass as necessary.

4. Click Move Center of Mass to display or move the estimated center of mass .

   You can click Reset Center of Mass to replace the mass in the center of the block.

5. Click Moments of Inertia to modify the mass moments and products of inertia.

   The Moments of Inertia dialog box appears. Modify moments and click OK.

6. Click .
   Sketch block mass properties are used only for two-dimensional motion of layout sketches. Three-dimensional parts made from blocks use the assembly Mass Properties.

7. Click to close the layout sketch.
