The search for FeaturePatternElement is based on the reference to the projected sketch circle is performed by the function GetEltByGreenCircle. If the path represents a projected hole’s pattern element and its property AddsMaterial returns True, then the corresponding pattern element is suppressed. The rule analyses every profile path in the profile object. It then calls the AddForSolid method to create a profile object based on the combined projected geometry in the transient sketch.ģ. (For simplicity the rule works with the first rectangular pattern in its parent part document).Ģ. The Main function projects the boundary geometry from the planar sketch “Boundary” and all the elements of the holes pattern into the created on-the-fly transient planar sketch. After the rule is run, the holes outside of the boundary are suppressed.
DEFINED BOUNDARY FULL
In figure 5 you see the full rectangular pattern. (Any language that can access the Inventor API could have been used too). To demonstrate this approach I used an iLogic rule. (Fortunately there are not any restrictions on the geometry of the profile paths). This powerful built-in topology analyzer of the AddForSolid method you can be used to easily identify pattern elements that are completely inside the specified boundary. Otherwise it subtracts material.įigures 3 and 4 show that this rule works for profile paths of any other geometry as well. If a circular profile path crosses the ellipse (boundary) or is located completely outside then it adds material to the solid body.
