I know you probably want examples illustrating this, but it is a little hectic right now so I will have to owe you, but I’m finding the more picky OSnaps a bit hard to deal with. What I am seeing most often is if I have extracted a isocurve, or placed a point on a surface, I often times can’t get a …

This one should work better in the next build. I increased the amount the osnap location is offset towards the camera before testing, and it makes osnap snap to things that are just behind shaded areas. There is no osnap visibility testing in ghosted or wireframe view, so there’s always a way to os…

Thanks Mikko, I’ll look for it in the next. Sam

This is working a lot better for me. Thanks for the tweeks :smile: Sam

I am having some issues with clipping planes and the new OSnaps. In the attached, try and get a near or mid snap on the lower edge of the box which is being clipped. Over here, I can’t get an end snap on one side either. I haven’t been able to find a reason or pattern as to why some edges work and s…

I have been meaning to get to this topic as well. In the attached pictures, I have a box that is inside a pipe (cylinder with wall thickness). The pipe is frozen but no part of the box can be snapped to (first picture) unless the view is such that that part of the box would be visible were the pi…

These should work better in near future WIP. I made osnap visibility testing pay attention to locked objects being drawn ghosted or behind normal objects, and see-through clipping planes.

Not sure if near future WIP means 6.0.14322.10041, 11/18/2014, but this is still pretty painful when trying to dimension a view with a clipping plane.

Sam, I’m not seeing the problem in ClippingSnap.3dm anymore. Is this the same issue or something different?

I’ve now installed 2014-11-18 and see that the case where the pipe is frozen is sloved; the box can be snapped to. But the problem remains when using a Clipping Plane. See attached file. box_in_pipe-snapping v6.3dm (328.8 KB)

Are you talking about a shaded view with “Show Fills” enabled for clipping planes? I hadn’t done anything to that yet, because the osnap code has absolutely no knowledge of where those fills are. For the next build I’ll make the visibility testing always obey the clipping planes. That should make i…

I found and fixed the problem. The visibility testing wasn’t paying attention to clipping plane orientations properly, and didn’t obey per viewport visibility, like HideInDetail.
