Modifying Geometry with the Intersect Tool You can intersect solids, surfaces, and planes to modify existing geometry, or to create new geometry with the Intersect tool. For example, you can add open surface geometry to a solid, remove material from a model, or you can create geometry from an enclosed cavity. You can also merge solids that you define with the Intersect tool, or cap some surfaces to define closed volumes. Open surface and a solid body Two halves of a mold The open surface defines details that you can add to the body with the Intersect tool. The empty cavity enclosed by the two mold bodies defines a body you can create with the Intersect tool. You can remove the geometry you do not require with the Intersect tool. You can remove the mold bodies and create a solid from the empty cavity with the Intersect tool. To create geometry from solids, surfaces, or planes in a part: Click Intersect (Features toolbar) or Insert > Features > Intersect. Select solids, surfaces, or planes. Click Intersect. Select the regions to exclude and click . Contents Intersecting Bodies to Modify Part Geometry You can intersect and merge surfaces, planes, or solid bodies in a part with the Intersect tool. For example, you can add details to a body by merging it with a coincident open surface. You can also split a body by intersecting it with a plane. Creating Solids from Enclosed Cavities You can create a solid from a cavity by merging coincident surface or solid bodies in a part, and then removing the geometry defined by the bodies that enclose the cavity.
