Object Snap Culling Issue

brady1 · December 13, 2022, 3:12pm

Trying to throw some dimensions onto layout space using a front view detail of my model and noticed that the snap culling is not functioning or a setting is turned on/off. The cursor keeps wanting to snap to objects behind objects. I cant find a snap culling setting in the options menu. As usual, not sure if this is a bug or a new feature that I don’t understand yet?

Gijs · January 3, 2023, 1:05pm

hi @brady1 thanks for reporting. The setting related to this is Rhino.Options.ModelAid.SnapToOccluded and this indeed seems to be broken
RH-72252 Rhino.Options.ModelAid.SnapToOccluded is broken

This issue still persists. Any news of a fix?

Hi Brady -

Please run the Rhino SystemInfo command and copy-paste the result here.

Thanks, I put it back on @mikko’s list to look at.

mikko · February 20, 2023, 9:45am

@brady1, please post a simple 3DM model demonstrating the issue. Preferably with just two objects in it, a shaded object and the object behind it getting snapped to.

brady1 · February 21, 2023, 1:44pm

I can’t recreate the issue with a new “simple” model oddly enough. But I will upload one of my simplest project files to rhino/upload.

brady1 · March 15, 2023, 2:54pm

I just downloaded the lasted WIP and still the problem persists. I am uploading my file via Rhino upload, maybe its just a problem with my file?

@brady1 I looked at your file, all views are in wireframe mode, so in that case there is no occlusion. Is that what you expected?

brady1 · March 21, 2023, 12:02pm

No I use a custom display mode sorry. Put in rendered mode

Gijs · March 21, 2023, 1:19pm

can you send me that?

Hi @brady1 it turns out that the active clippingplane for that view is causing issues.
I logged RH-73739 ClippingPlane causes issues with Osnap

brady1 · March 21, 2023, 4:25pm

Interesting! In my other files the snap culling issue does seem to be fixed. Thank you Gijs.

brady1 · May 15, 2023, 5:22pm

I am noticing the snap culling issue again. Occluded objects are being snapped too and objects in the foreground aren’t being snapped to at all. Using WIP build 5.9.23 see vimeo link
