Yes, it does happen in a new drawing with primative objects. The only thing I have noticed that seems to degenerate is the Join command. After drawing for awhile, it becomes ghosted and will not come back. I close the program, and reopen it, then the Join icon is no longer ghosted.
AFAIK, snapping to 3D objects never works, and never has worked. How do you snap to 3D objects?
Would Vista 64 make any difference? I am runnning it.
Please comment on fixing up my workspace. I have noticed that when using Workplane on Facet, the x,y,z coordinates do not always match up with the little icon in the lower left corner when using the bar on the bottom of the screen to change object sizes or positions.
I have attached a part of my drawing. I cannot snap to anything on the hollowed cylinder. I am using the cube to snap to facets used to create the spiral with the Rotate command. The circles were used to construct the hollowed cylinder. I need to be able to create a point located precisely in the center of both faces of the hollow cylinder.
Not sure what center of extents is.
