Hello! Could you please check why SelBoundary is not working on that hatch? SelBoundary bug.3dm (159.2 KB) I just left one hatch in this scene, but others failed, too. Thanks!

If you choose the Crossing option, the Cyan curve does select the Hatch with SelBoundary. If you select the Hatch and run a BoundingBox command, you see the box overlaps outside of the Cyan curve. That’s why a non-crossing selection window fails. In this case, SelBoundary uses the BoundingBox of t…

I would certainly call that “undesired behavior”, but the tool is working as designed. Based on that, I would characterize it as a “limitation”. There are a variety of objects including Annotations (text and dimensions), that have the same designed limitation. I wish it was not that way, but once …

A hatch has a specifically defined boundary in the same way that a planar surface does. I see no reason why a hatch should work any different than a surface in that regard.

I agree! I’ve filed defect reports on this in the past and they were turned down. It’s Sunday afternoon and I’m watching the ball game. It would be a waste of time and would raise hopes if I added another report to the pile.

@Eugen I hacked together a script based on a volume selection script I made recently - basically it converts the closed input curve into a volume by extruding it in the view CPlane’s direction and then tries to select the objects inside the volume. Works on your example above. May be slow with lo…

Thanks, that works! Quick, are we… =} Nonetheless, it’s pretty counterintuitive and less practical that SelBoundary has this ‘limitation’ of only working for the bounding box. In my usecase, I wanted to speed up the hatch trimming process by selecting all hatches (thousands) completely inside some…

Here’s another one: SelBoundary works for components, too, as it seems: [image] Which is cool! (I turned on Sub-objects in the SelectionFilter panel) However, when the boundary is not a circle but a polyline, how would I select the whole closed polyline that the SelBoundary command asks for? [i…
