Grading is not reaching target surface

[leonardo.murte]

Hi there, 

I have been having this problem for a while, when I am using the tool Grading to create surfaces with a slope, it does not reach the target surface.

The green profile represents the surface created with the grading tool, for a reason it does not reach the red dashed line (target surface). The incomplete surface is the one with yellow and red contours.

Then I created another surface with the same slope but this time I targeted distance then I found the intersection between that new surface and the existing ground and the result is the magenta line.

any idea why the grading tool is not reaching the target surface?

Regards, 
Leonardo

Hi @leonardo.murte,

Welcome to the Autodesk Community and thanks for posting. Can you share/post your drawing for testing?

Hi,

I am having the same issue. It is a simple grading task for a quick cut/fill analysis and grading to my existing ground stops about 50ft away from the grading feature line of my pad edge, but in a circular extent. Initially I thought there may be some type of constraint I set without realizing it. So I recreated the site and still get the same result. I didn't experience the same error on any of my other testing sites, only this one. What setting or parameter could stop the grading before it reaches the target surface?

Hi @rmacan 

I found a solution to this problem.

Add a small curve on that corner (Feature line). After that, you may need to add some elevation points along the curve to help the grading target the Existing Surface.

Sample_1 shows the current grading target coming from a 90 degrees angle, so only the Orange line targets the other surface, and the area between those intersection points is only a projection.

Sample_2: If you add a small curve on the feature line, even a 0.01 radius, and add some elevation points along the curve, the model will find the intersection point perpendicular to the elevation point. (Yellow dots are Elevation points, and the Purple lines will be the projection that will help you to trace the right target.

If that solves the issue, please select this post as the answer. Thanks.

Hi Leonardo,

I am not seeing how to select your post as the solution, but you nailed it.  I added a small fillet the the feature line corner, and then add a few elevation points to it. After refreshing, it now extends to the target surface as expected.
Thanks!
