Circle area selection?

Hi all !

I want to get all pins, vias, clines, vois in a circle selection area, but I don't know any way to do that, I only know the function checking in box selection area ( axlSingleSelectBox).

My purpose : check in a circle selection area if there is any item(pins, vias, clines...) or not?

How can I do that, please help me, my allegro is ver16.3

Tks,
Luan

There is no function to do that. The way I would approach it is:

Use the cursor dynamics functions to allow the user to select a circle. Convert this circle to a polygon.
Select all the objects in the bounding box defined by the extents of the circlular polygon.
Step through each object, creating polygons from it, and use axlPolgonOperation to AND them with the circular polygon. If the result is not nil some part of the object is in the circle.

Hi eDave!
Thank for your suggestion, basing on your idea, I have checked elements by circle selection area in another ways.
