Cut Plane Modifier - Part Builder

[boutlaneyoussef]

Hello everyone,

Can anyone have any idea how to use cut plane modifier in part builder ?

I'm following the Help instructions but it does nothing.

Thanks in advance,

Just to give more information about what I'm trying to do.

I want to model a headwall for a box culvert like you can see below :

In part builder, I have modeled this :

Now I need to use a cut plane to have the appropriate slope for my wing wall.

----------------------------------------------------------------------------------------------------------------

P.S. : I tried modelling the wing wall using different methods. For example, i used a custom work plan representing one of the wing walls faces.

I have modeled the part like this (this is what i want) :

However when I insert this structure in my drawing, the wing wall and the rest of the structure are modeled separately : 

 Thanks in advance.

I am facing same problem. Can someone help?

This is one of those curiously (and inexplicably) top secret subjects that (apparently) no one who knows is allowed to discuss publicly under threat of grave bodily harm, or something.

I've come to the conclusion that the closest you can get is to approximate the shape you're looking for with a Transition between two rectangular profiles, one at the face of the endwall and the smaller one at the end of the wing.  The end will be parallel to the endwall, instead of being perpendicular to the wing wall face, of course, but that seems to be the closest you can get.  (I do hope to be proven wrong about it.)

It hit me after (finally) finishing this endwall, that it should be relatively easy to put a small, triangular extrusion at the end of the wingwalls to make the ends perpendicular.

If anyone is interested in the intent, this is a  PennDOT Type D-W endwall, RC-31 in Publication 72.  This ONLY handles the Skew 90-60 degree scenario for each pipe size from 36" to 72".  Each skew will have to be another part.  I believe they could all be done in one part, but I'm out of patience for it, as this was mainly a learning exercise for myself for now.

If anyone wants any explanation on specific aspects of what I did, I'd be happy to share.  I don't have the time to write it all up at the moment, or I would give that a try.  I hope someone finds this useful.  It's really unfortunate that the documentation is so bad on Part Builder.  One key thing is that you cannot have non-orthogonal work planes.  I spent several hours trying to cheat one in, and that didn't work.  Also, I had zero success with cut planes.  They simply did not do anything.  If it was something I was doing wrong, I would LOVE to see how they work.
