I think this is a new feature request, unless there is already a well hidden way to do this.
An optional toggle button (that always defers to the current behaviour) to allow drawing tools (e.g. circle/polygon/rectangle… and maybe the rotate tool?) to move between:
1 - orientate to red/green/blue plane, depending on camera angle
2 - orientate perpendicular to the most recently referenced line
3 - orientate parallel to the most recently referenced face (or referenced line and the blue plane?)
4 - orientate to the exact angle that the camera is looking from (as if current view is plan view)
This would solve 2 problems I have:
I have a long a tedious workaround to this problem, but does anyone have a faster way to draw a circle perpendicular to a line that is NOT on either the red/green/blue axes.
For example, I have a wire frame and i want to draw a circle with this line at its centre, but sketchup automatically draws all geometry to snap to either the red green or blue plane, depending on camera angle. Therefore if I draw a circle on one of these axes and use the push/pull or followme tool, their will be an elipse rather than a circle that follows my line. (I currently use the line tool to make a perpendicular box to orientate the draw tool with, or change the axes temporarily - both of which are a faff)
The second thing this would solve is the ability to rotate the model better. Though the current behaviour is intuitive and logical for drawing (with only rare issues like the above), for rotating the current behaviour can be counter-intuitive. If the rotate tool could be (optionally) set to rotate on the plane you are LOOKING from, with would allow much more easy and powerful manipulation of complex objects.
For example, I’m currently bending the fingers of a hand, and I’m looking from the right angle that I want to rotate from, but finding it difficult to find a face to reference to get the rotate tool to do what a 2D drawing package would. (I understand sometimes this might make things appear to have worked until you re-orient the camera and see what you’ve really done… but it’d be another avenue to pursue to achieve sometimes complex tasks, and therefore sometimes the best way, and sometimes not…)
PLEASE PLEASE pretty please
Thanks for your time!
