I am new to VW and am working through the learning curve. A clarification please. Are objects being drawn always on the working plane. I seem to be experiencing situations where I have set the WP to a specific surface; yet the drawn objects (and subsequent extrusions) appear at some distance in front of or behind the WP. Is it possible I have mistakenly configured VW in some way such that objects are created at some distance from the WP, or is this simply not possible Thanks Dave
