Trim Feature
Trim feature is applied to remove portions of an existing surface feature. A trim feature is similar to a solid cut. Following are the existing types of feature creation for the trimming of a surface or a quilt.
• Use Quilts—Cuts a piece from a surface using an intersecting quilt. Creo Parametric consumes the quilt that is used to trim a surface and allows you to keep either or both sides of the trimmed surface. You can trim quilts in the following ways:
◦ By adding a cut or slot as you do to remove material from solid features
◦ By trimming the quilt at its intersection with another quilt or to its own silhouette edge as it appears in a certain view
◦ By filleting corners of the quilt
◦ By trimming along a datum curve lying on the quilt
• Use Curves—Trims a surface using selected curves and edges.
The rules for defining a surface trim using a datum curve are as follows:
◦ You can use a continuous chain of datum curves, inner surface edges, or solid model edges to trim a quilt.
◦ Datum curves used for trimming must lie on the quilt to be trimmed and should not extend beyond the boundaries of this quilt.
◦ If the curve does not extend to the boundaries of the quilt, the system calculates the shortest distance to the quilt boundary and continues the trim in this direction.
• Silhouette—Trims a surface at its silhouette edge from a specified direction.
