Feature Line - Offset to Intersecting Slopes

Postby Lincoln » Fri May 22, 2015 1:23 pm

Here is a new command idea that would be very useful for grading design:

Two feature lines running adjacent to each other, at some varying distance apart.

Examples:

Could be a Toe featureline at the bottom of a slope, and then a Top of Bank feature line.
Could be a feature line wrapped around a building pad, and another feature line out some distance representing the Back of Sidewalk.

New Command:

The command would create a new third feature line between the two feature lines at some User specified grade away from the First feature line, and at some User specified grade away from the Second feature line.

User would be prompted to pick First feature line and give the desired slope away (i.e. 3:1) from it.
User would be prompted to pick Second feature line and give the desired slope away (i.e. 10:1) from it.
New feature line would be created at (i.e.,3:1) from the first feature line, and (i.e. 10:1) from the second feature line.

We would want to see the temporary green glyphs and red vectors that the current Civil 3D feature line edit commands use. These temporary graphics would show us where the new feature line would be placed, so we could make slope adjustments on the fly within the command if needed before committing to producing the third feature line in the drawing.

If you can, email a small DWG example so we can see the desired results.

Essentially the intersection between two planes?

Taking this a little further it would be useful to be able to do a simple grading to a surface and produce a featureline without all the baggage (and crash potential) associated with gradings.

Sometimes a dynamic grading isn't necessary (or desirable) and a quick and dirty Featureline is all that is required

That's not taking this one further...! That's a specific separate command..

That is the old and very handy Daylight Polyline routine from LDD. Dotsoft could easily do that I'm sure..

Yes, this is essentially folding plane grading without having to create surfaces just to do it.

I'm not familiar with LDD but a simple couple of clicks to see location of the top/bottom of the slope and then generate a 3D poly or featureline would be very useful to me.

Yes, that needs its own thread topic:
