Lines in true 3D?
Lines in true 3D?
(OP)
I'm running MDT6. If I have an part in model space, and I try to draw a line from an entity of that part, it places that line on my current UCS, not on the actual part. Likewise when I try things like distances requiring X,Y, and Z values, I only get X and Y, with a Z of zero. It isn't recognizing the Z direction.

Where ever the UCS icon is, Autocad determines that point of being 0,0,0. Oblviously, your line is object snapping to that point. If you want to put a line on the 3d object then move the UCS to that point. The command UCS and the O (orgin) option is the way to go at the command prompt. Notice that you can only sketch a feature or create a dimension in the XY plane only. Hope this helps - John

One of the basic functions of the geometry calculator is vector expression. The CAL command can be used transparently (within another command) to determine the end of line of xyz coordinates by putting an apostrophe followed by CAL. For example, the CUR function is used to specify a point picked with a cursor.
Command: CAL
>>Expression: CUR + [1,1,1]
(point coordinates)
Point coordinates represents the point coordinate values returned by Autocad. Hope this helps - John
