First, apologies for erroneously sending this as a message to all members before... wrong button!
My question: is it possible to remove additional curves/holes from slabs that have been added/punched by "Add Boundary" / "Subtract Boundary"?
There must be some internal curve list in a slab. Do we have access somehow?
Deleting points is not possible as it seems.
You can remove the holes you have created in slabs by adding a new boundary curve that covers completely the hole substracted.
That's how I did it anyways... yet how does this work "internally"? Are there more and more boundaries (slabs and holes) that look right in the end, but still prevail, or is there some recognition that the new slab matches a hole and thus the hole is effectively removed from the list?
Once the hole is covered with a new boundary curve, the control points on the slab from the curve used to do the subtraction are no longer available. The same happens when any part of the slab is covered or subtracted with a new boundary curve. Why do you need the full list of curves used on the slab?
Would it work for you if slabs behaved like polylines, so when you delete control points, the boundary were recalculated ?
Yes, that would be the simpler and much more intuitive approach - being able to delete /add slab control points! A boundary (slab or hole) then is removed if one deletes all points (or less than the minimum number required for a closed polyline) of it.
Having to duplicate a hole's boundary and adding it again to the slab is kind of awkward.
Do you think you can change that?
All right, we will consider this option for future versions of VisualARQ. I agree that it would be easier and more intuitive than it is now.
