I'm working on an upgrade survey in Civil 3D. The basis of the drawing was done in Land Desktop. The old Land Desktop points are not points in Civil 3D but blocks that appeare as "AECC_POINT" points while the new Civil 3D points appear like "Cogo Point" points in the Design tab of the Properties window. The problem is:
1) I need to convert all the old "AECC_POINT" points to "Cogo Point" points that work in Civil 3D.
2) Then I need to raise the elevations of these "new" points by 0.26 feet so that they are all in the same datum as the rest of the "Cogo Point" points.
I'm new with Civil 3D with a backround in Land Desktop, so I'm riding that steep learning curve as many of my surveyor colleagues. Any ideas?
Solved! Go to Solution.
On the Home tab go to Points and the 3rd from the bottom with say Convert Land Desktop Point.
If you have the older project files for the site that would be better than converting the points, as this tend to cause issues sometimes with C3D.
As far as the elevations change goes, you have 2 options, Move the points from 0,0,0.26' should adjust them (depending on version), or you can export you new 3D point to ascii, by right-clicking the point within prospector and then importing they point file to a survey database were you can then translate and rotate as needed.
Hope that helps.
To change the Datum you can select the points. The contextual tab for COGO Points should come up. Under Modify you should find Datum. That will let you enter an elevation boot for the selected points.
When you convert the Land Desktop Points I believe there is an option to add to a point group. I would use that, make a new group called "converted from LDD" or similar. Then you can use that point group to edit the points, knowing that you've got them all, and none of the ones you don't want to change.
Credit where credit is due! Give kudos or accept as solution whenever you can.
Thank you! I managed to use the Convert Land Desktop Points command as AllenJessup suggested. Creating a Point Group was the best thing to do before following his advice. I also found the "Changing the Elevations of Points" article of the Help file very useful!
Yes. Add them to a point group when converting is best. You can also create the point group after converting if they are constant with numbering and/or description. At least get them on an individual layer so they're easy to select.
I didn't know that little button was even there, guess that comes from just using the Survey Database and keeping things locked so that dont move unless I want them too (Translate). Im not a big fan of the SDB but its the only solution for automated linework, and in general once things are in and translated nothing needs to move anyway.
Now I had tried things were you import to SDB and then import to drawing, but think the SDB just removes that step, If only you could detach the block from the node in like a drag state things would be peachs and cream (when symbols overlap for utilities and the like).
