changing the elevations on a job

Postby tommyh » Sat Sep 17, 2016 1:30 pm

Hello, i'm a newbie here, I recently had to do a topo of a park. At the time i was not provided an actual benchmark elevation. Therefore I used
an arbitrary datum. I have now been provided with an actual job elevation. The difference in the arbitrary datum and the actual is 7.77
I now must change all the elevations in my cad drawing by 7.77. My question is : How can I change all 330 points to reflect the new elevation ?
I do not want to change each point individually . I hope this is not a stupid question, i'm an old surveyor and never had to do this before.
I appreciate any help. Thank you.

At the command line, type CFU and look for "Elevation for Points."

The "differential" option should do it.
