With the Live Parts™ for SOLIDWORKS Add-in, users can define fixtures that lock (or fix) the cells that contact specific surfaces in their Live Parts design. When a surface is fixed, any cells that touch it are prevented from moving in all directions. In future releases we anticipate adding partially fixed degrees of freedom to allow for sliding and other constraints. You can define forces using the method outlined below.
- Select Fixture in the Add-in toolbar.
- Click on the Surfaces box and select the surface(s) in your SOLIDWORKS assembly to which the fixture will be applied.
- Click the Checkmark on the top of the fixture menu to accept the changes.
Notes on fixtures
- Users need to create at least one fixed surface in a Live Parts model. This surface needs to touch at least a few cells in order to anchor the part. There are two ways of ensuring that at least some cells touch a fixed surface. The first approach it to use a connections feature to connect each fixed surface to each forced surface. The connections feature will produce a seed cell on each fixed surface and this will anchor the part. In addition the user may want to add a fill zone that touches the fixed surface to ensure that cells growing from the seed cell (produced by the connections feature) will fill in a desirable shape. The second way of ensuring that a cell will touch the fixed surface is to use a seed cell feature instead of a connections feature. The user will place the seed cell on a user selected datum point, and this datum point should created on the fixed surface to ensure that the seed cell will be anchored.
- The connections feature provides an easy way of creating seed cells on each fixed surface. However, you may not like the placement locations of the seed cells produced by the connections feature. In this case you may create seed cells manually to precisely identify the start locations of your seed cells on the fixed surfaces.
- By using the connections feature, you may end up with multiple seed cells emanating from a single fixed surface. This is to be expected in that cells on each fixed surface need to be connected to cells on the forced surfaces.
