Grading tools

Hi all.  I have a building pad  with a feature line around it.  outside of that area, I have a fence line that is not a constant distance from the building.  I have created a feature line for the fence and assigned the elevations from the existing surface.  How do I use the grading tools to grade from my building to the fence line at whatever slope it requires.  I only see to grade to surface, distance, etc.  Can I have Civil3d grade from the building feature line to the other feature line?

Silly me... Thought about it more and all I need to do is select the two feature line and add to proposed surface.  Duh!

That is so funny.  I am doing EXACTLY the same thing, building, fence, grading, blah blah blah, and was about to post the same sort of question....and then I saw your solution.  And I've been sitting here for about 40 minutes thinking...about...it....and I suddenly understand why that would work.  Too funny.  🙂

Adding the featurelines as breaklines is a good solution. If you wanted to include the transition area in your gradings you could create an infill between the featurelines. That of course would require the area to be enclosed. Why would you want to use an infill? It comes into play if you want to use the Balance Volumes tool which only works with gradings, so you would need the infill for that area to be included in the volume calcs.

ooh, that's a good idea, and helps me with a different question I had....handling the transition between some of my gradings.  I can grab those feature lines and use an infill.  I like it.

 

Thanks Neil!

You can add an infill to any enclosed area as long as the bounding featurelines are in the same site. For open ended areas you would have to come up with a scheme to close it that works with the grading plan.

You can infill all FL grading and keep the clutter out of you surface definition

What do you mean, Joseph?  Do you mean grab all of your feature lines resulting from grading, toss out the grading, and then infill them?  Is that what you do?

 

By the way, what is the best way to 'snag' or keep a feature line from grading, if you plan to delete the grading?  Just copy it to a different site?

There is another benefit to using infills that I should mention. When you add the infill, that area becomes interactive with other gradings. For example if you have a building pad with gradings around the perimeter, by adding an infill to the interior, then any gradings that intersect the pad will be intercepted and form a seam.

Hello TK

 

What I mean is  if you create a grading with a surface, you can add FL's in the same site as the grading and they will automatically be added as gading data to the surface without having to add FL to the surface definition. I dont know if it a real beifit, but it makes organizint the definition easier. edit the FL the grading updates and thus the surface updates

 

I just dont like looking at the def tab and seeing oodle and oodles of lines.

Thank you

I was not aware of that behavior Joe. When you consider how the grading topology rules work it makes sense. I did test it to verify it works as you say.

I'll be thinking about the pros and cons of this.

One Kudo for you

I would throw in the usual caveats about the bugginess of the grading object and the inevitable crash that will occur when using them. ..😐

I concur Neil, but will add: in my experience it is mostly with projection grading; infills have been stable for me. Unfortynately, infill gradings don't seem to like being tied to dynamic FL like alignment/ profile yada yada
