Determine if Sketch Suitable for Feature Example (VBA)

This example shows how to determine if a sketch is suitable for use in a feature.

 

'------------------------------------------------

'

' Problem:

'       Sketch geometry can be used in a variety of ways in SOLIDWORKS.

'       However, not every sketch is suitable for every purpose.

'       For example, (non-thin) extrusions require a closed profile.

'

'       This code shows how to check a sketch to determine

'       if it can be used in various features.

'

' Preconditions:

'       1) Part or assembly is open

'       2) Sketch is selected

'

' Postconditions: None
