TOPO Cobined Fator

[Anonymous]

I’m a binger in Civil 3d. I am facing one problem with TOPO Combined Scale Factor.

The received combined factor scale is  1: 0.999591760. how can I set this value in Alignment sheet without changing the display STA.

For example, the STA value =1+100, 1+200,1+300 …. (That means the distance between two point is 100.00 but real distance is 99.959 as per combined factor). I need to keep STA in  1+100, 1+200,1+300 style (round figure) with maintain real value 99.959 in manual measurement. see attached figure

I appreciate your help and support.

best regards

Are you trying to mix both grid measurements and ground measurements?

That is going to cause problems.

If your design is in grid, it would be best to do the entire drawing in grid, and if you need certain objects labeled in ground units, then use a label style with your CSF applied to the measurement. Also to prevent confusion, you could add "(Ground)" to the style so those measurements are very obvious.
