Grading problem

[novais]

Hello,

I'm trying to make a plataform on a landscape. If i do the grade to surface using a feature line with the elevation i need, it all comes well (cut slope 1:1 and fill slope 2:1).

But if i try to use my polyline (limit) as feature line with assigned elevations of my surface, and grade to pretended elevation (inside de feature line), the slopes generated  are wrong. It draws a cut slope on the fill zone and it draws a fill slope on the cut zone.

The slopes are draw at reverse, even the inclinations.

has anybody got a clue??

Thanks.

What version are you using? 2010/2011/2012?

Do you have any images to help explain your problem?

I've made a feature line with assigned elevations to the terrain surface, and then i created a platform doing a grade to elevation (552.00) from the feature line to the inside using a 1:1 cut slope (red) and a 2:1 fill slope (green).

The slopes generated as you can see in the pics are misplaced, the fill slope pattern is on the cut slope and vice-verse.

In the quick profile (2º pic) you can see well the slopes, but on the cut side it's a 2:1 and in the fill side is a 1:1 slope.

If i make the grade to surface for the outside of the feature line for example, it all comes well.

Btw, i'm using ac3d 2010. I really need some light here....

Thanks

Why can you not just swap the grades around? i.e. use 1:1 for fill and 2:1 for cut.

This should give you your desired result.

Its a quick solution, because ac3d in this case considers the fill style aplied to the cut slope and the cut style aplied to the fill slope, but doesn't resolve the issue, it should do it properply, right??

Gee! I must be dense - where is the problem?
