Marking the delta elevation of a line

View Only

Hi,

For a current project I would like to make the delta elevation (max elevation - min elevation) of a linestring in TBC.

With the label style manager you have a lot of options like line lenght, azimuth for cadastral purpose.

Mine is rather specific to show the difference between a surveyed point and theoretical point on a BIM object.

Could someone help me? Do i need to do some coding?

If you say "theoretical" point on BIM object I assume you mean perpendicular to it. That's nothing you can do out of the box.

You can try my "SCR_PerpDistToDTM" from my GitHub repo (https://github.com/RonnySchneider/SCR_Macros_Public), that works with surfaces and BIM . Minimum license you need to run Macros is "Survey Advanced".

Hi Ronny,

Thanks for you answer.

I don't it's that complex. I draw a theoretical line from the surveyed point to the theoretical point. So there is a line and I just want to show the elevation difference between start point and end point of that line.

Wouldn't know a way how to do even this simple thing out of the box. The smart text's don't have a code for line start/end elevation.

Usually my demands are even higher, so I wrote me a macro for this kind of stuff. Doesn't need the line, just a design point and at least 1 as-built point.

Naturally it only creates normal text's which won't change if you change one of the points.

Are you able to add elevation to a point from the BIM? OR even create a surface from the BIM?

Could make those surface points into a surface and then compare it to the BIM.

Hi Ronny,

Your reporting tool worked like a charm! Brilliant.

Thanks a lot for the swift reply and your help. This does what I need.

Just would like to change dZ with just the Z= as text style but I assume I can find this in python coding.

Just change it in the green input field, where the tick box for Elevation difference is.
