Calculate Sum of Multiple Polyline Areas

Using Civil 3D 2011 - what is the command to add up multiple polyline areas or hatched areas (square feet) at one time?  It's quite time consuming to list each polyline individually and add up the areas by hand.

I've done this before, just can't remember the command.

Thank you.

Yeah regions work well but you can't edit them so it's a recreation for each revision. The new hatch editing commands make revision much easier. Add/delete verticies, grip edits, set boundary, generate boundary. These make it very easy.

 

We do get dwg errors when we hatch xref's but the errors clean up well with Audit or Recover.

I deleted my post about regions after I noticed someone else mentioned this earlier in the thread. You're are right about the new hatch editing features. What a great improvement.

Yeah. Well Regions can be edited but not that easily. I see that hatches are reactive and that's a great benefit. If and when I get back to this work I'm sure I'll be using hatches!

What commands are you using to edit the region?

Wondered when you'd ask.Smiley Wink

 

In the example I posted I'm using the Move command. It's a little tricky. If you hold down CTRL you can select one side of a Region. You can then use standard editing commands like move to affect that side. When I created the polyline I converted to a Region, I included a 0.001 unit length segment at each "Corner". I then held down CTRL and selected that segment using a Window. Then started the move command and it looks like I'm stretching that corner.

 

You can use the CTRL trick on polylines too. Selecting multiple segments to Move, Scale, Rotate or Delete.

Is there any way to get your method to work if all the line work, hatching, etc is in a base drawing that is xrefed into a sheet?

I would like the table to be in the sheet if possible.

Yes you can hatch well thru an xref ( you still require no overlapping objects, crossings and constant Z on all objects) but there are issues with hatching thru an xref that have been around for a while. I don't know if it's fixed in 16 or 17 but with 15 and lower hatching an xref leads to the Drawing Errors Found dialog appearing at saves, Audit_Bad_Layers will appear. These have been benign in my experiance and are typically fixed with an audit.

 

Big thx once again to @Jeff_M for helping me determine this issue when we were using 12 or 13.

Not for nuthin but the dATAEXTRACTION wizard can extract the areas of hatches across any number of XREFS and report in in a table in another file.
