POA Posted November 26, 2014 Share Posted November 26, 2014 So this is a process question, rather than a specific issue but I will use the most recent attempt as an example. I was trying to create a sloped ceiling following the slope of the stairs but offset 2700mm above. I really couldn't figure out how to get either a slab or wall element to do what I needed (by drawing them and attempting to use 3d-reshape), so I decided I would model the ceiling using the 3D modelling tools. To do this I used the clip cube to create a 3d section through the stairs, set the back wall to be the working plane and started to draw. This is where I got stuck, I wanted to draw a line along the top of the stair risers and move it up 2700mm as a guide for the ceiling line but I couldn't get it to snap to the wall/stair junction. How do I do this, what is the recommended process for using existing elements as guides to model accurately. I have had similar problems in other situations and being a sketch up user Im used to this being a pretty simple operation Any suggestions would be welcome. Quote Link to comment
bcd Posted November 26, 2014 Share Posted November 26, 2014 Are you drawing in Open GL on? If so the issue/feature you're experiencing is the Occluded Snapping - which limits the number of snap points - theoretically to those on front/ visible faces. You can turn this off completely VW>Preferences>3d>Use occluded selection & snapping or momentarily disable it by invoking the x-ray mode (b key) and snap to the required points. Make sure your not drawing in Screen Plane. Quote Link to comment
POA Posted November 26, 2014 Author Share Posted November 26, 2014 bcd, thank you! That fixed it perfectly! Before I switch this thing off and condemn it to obscurity, is there anything that it is useful for? Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted November 26, 2014 Vectorworks, Inc Employee Share Posted November 26, 2014 It is used for placing things on physical surfaces. If you were fleshing out the detail objects in a room or doing interior work, before Occluded Snapping it was easy to place bowls and chairs and things accidentally halfway into a table or through a wall without noticing, this option prevents that but wouldn't be useful when doing what you describe in the original post.

POA Posted November 26, 2014 Author Share Posted November 26, 2014 Jim, Ah, thanks for the clarification. Perhaps worth remembering that one then. Many thanks for the help. Quote Link to comment
