Paul Mc Posted November 7, 2022 Share Posted November 7, 2022 Is there a way to display a dimension showing the difference between a point elevation and a 3D line elevation? Quote Link to comment Share on other sites More sharing options...
CyberAngel Posted November 7, 2022 Share Posted November 7, 2022 Do you want to measure to the nearest vertex of the 3D line, to the nearest point on the line, or to a specific point that depends on something else? Are these two locations guaranteed to have the same X and Y values, just different Z values? If I had to do this, I'd set my UCS to XZ or YZ and create a rotated dimension. That might be tricky if there are many points to dimension. It would help to know more about the line and about your goal. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted November 7, 2022 Share Posted November 7, 2022 A maybe is, if you convert the lines to a surface can get a Z of a point based on surface, using X & Y. So compare 2 points. Needs say CIV3D. Can be done as a 3dface using math formula much more involved. A point directly above / below a 3dpolyline, need to get which 3dpoly segment matches, can then work out Z value. It is sounding like multiple points, if only say pick, pick, then Cyberangel solution is way to go. Paul Mc please advise lots of points or not, maybe post a sample dwg.
