Simpler sloping of pad?

[rhaught]

On about every project at work I need to take a strangely shaped pad and give it a 2% cross slope.  I have been doing this by manually editing the elevation of points on the feature line defining the edges of the pad and watching the surface slope labels adjust until it works.  Is there an easier way to tell a feature line to slope between two points not on the same segment?  This seems like the kind of thing there would be a command for somewhere.  Thanks for your time.

R,

How about making a 4-sided surface (infill) that slopes the way you want, and then draping the strangely shaped pad onto it?

Yes, checkout the WorkingPlane tool:

I can certainly vouch for the usefulness of this tool....:)

Create a simple two point (line) feature line outside your "pad", offset or use a grading object to create a 2% plane from that feature line, across the pad area, then create a temporary surface from these two feature. The temporary surface can be set to a non-visible style, so you don't see it. Then drape your pad feature line on this temporary surface to assign the elevations. Voila, you have an irregularly-shaped pad at a nice 2% slope.

I like to keep the temporary feature lines and temp surfaces in their own Site, and on unique layers, so that I can turn their visibility off and/or freeze the layers, but still retain them in case I need to make revisions down the road.

.....or just use Jeff's tool which automates all this

Pinward's strategy works.  Thanks a lot!  But Jeff's program also looks like it might help a lot.  I got it installed and am experimenting with it now.

It would work as it is what you need to do, Jeff's program automates it significantly....;)
