Use the Boolean tool to combine solids, subtract one
solid from another, detach solids, and find the intersection out of
the solids.
Use Parasolid
When you click on the Boolean tool, you will have the option to either keep the
common interface or to use Parasolid. Figure 1.
This option is added to allow you to use the Parasolid geometric kernel for
performing boolean operations like combine, subtract, and intersect.
Key Differences
Here are some key differences between using classic and parasolid geometry.
When complex geometries are submitted for this operation, using the parasolid option
can return with partial success creating regions of the failure areas in the
Model Browser. The following image shows a few similar
regions as an example. Figure 2.
You can review problem areas and either fix or isolate them by trimming solids so
that the remaining solids can be successfully processed for the boolean
operation.
If the selected solid has a common interface to another solid that is not selected,
that solid is not considered using the parasolid option. For the classic geometry
engine the solid that interfaces with other unselected solids is still considered in
the boolean operation. Figure 3. Combine with Parasolid Option ON Figure 4. Combine with Parasolid OFF
In the following example, the selected solid has a common interface to another solid
that is not selected. That solid is not considered using the parasolid option and
the common interface is removed by detaching these solids. For the classic geometry
engine, the solid that interfaces with the other solid, though not selected, is
still considered for the boolean operation. Figure 5. Combine with Parasolid Option ON Figure 6. Combine with Parasolid Option OFF
