Feature Line from Grading

[neilyj666]

I created a grading but now I want to use the "daylight" line (as a featureline) and delete the grading (due to stability problems I was having yesterday (C3D hung for 2.5hrs, I went home and VPN'd into my work PC).

Can the daylight line be extracted without exploding the grading as I'd prefer to delete the grading via the Delete Grading on the toolbar as this seems to be more robust than trying to delete the exploded entities??

I do not know how to extract the daylight line but I have had very good success exploding the grading by selecting the daylight feature line. If I select other portions of the grading when exploding I get less than desirable results. AS you probably know after exploding you are left with a 3d polyline. I like to turn that back into a feature line.

A new command "Extract feature line from grading" is what's required.....

[JeffPaulsen]

I second that. I would have used it 5 times already today.

If it's something you use often, perhaps a little Third Party help would be in order?

Not able to buy anything unfortunately but there are a whole raft of addons in the Sincpac that offer functionality that really should be included as part of the core C3D product....but isn't

Save drawing, explode, copy to coordinates (say, 0,0), close, re-open drawing, paste (to 0,0), convert polyline to featureline.

Then just Delete Gradings.

Use the stepped offset command, and offset it a very small distance (0.001).

Select the Daylight Feature line, right-click and use the Move to Site option.  This method will delete the grading object, or you can use the Copy to Site command if you want to keep it.

Once you have cleaned up the grading objects you can move the daylight features back to the original site.

This looks like a good suggestion....

I'm not keen on offsetting objects very small distances as it becomes a bit of a pain keeping track of them
