<See page 3-60 of the manual. Vertex snap snaps only on the 2D plane. To snap in 3D, you need to use two operations in two views. The ortho views XY&Z are best. If you are working with a non-axial user view, each snap may move the previous point off the vertex.> This is the first place I looked for a solution, but it says: " Vertex snap works only on the 2d plane displayed in the active viewport…to snap two vertices in 3d space, either perform the action twice, using two orthographic viewports, or use vertex snap in the ususer viewport" which indicates to me that 3d snaps are available in the user viewport. I use the user viewport almost exclusively for all work requiring vertex snap or welding operations and had have found that almost without exception the 3d snap works fine. I have had problems on two occasions however, when the vertices only moved in one plane. Andy

Andrew, It has been my experience that as stated in the manual "Vertex snap works only on the 2d plane displayed in the active viewport". The active viewport could be the user view or any orthographic view, but vertex snap will still only move vertices in the XY plane of the current viewport. It may have worked for you at times when your vertices were already coplanar in the curren view or they ended up closer than the weld distance. Terry Gilbert Forcade & Associates

I would be curious to know the results if you tried testing this out yourself. Andy

<Your right. The User view _does_ snap in 3D. the ortho views are 2D only. > This being the case, I guess that the reason I was occasionally getting a mere 2d snap in the user viewport is that I wasn't actually close enough for the vertex to activate the snap, but was close enough that it seemed to work, so operator error.
