Insertion Rim Behavior Question

[cloquet]

Under Structure Properties, I go to change the Insertion Rim Elevation, set it to false, and then enter my calculated top of casting elevation...but as soon as I hit apply it jumps back to it's defaulted elevation.

I know the reason has something to do with the surface, but can't figure out how to fix it???

Is there a way to get around this so that I can enter whatever elevation I have calculated?

Thanks.

Did you setting the reference surface to none and then set the rim elevation you desire? That has worked in the past for me.

[cloquet]

Yes...under the Pipe Network Properties, I changed the Default Surface to none, but when i created the Network I had a suface assigned.

Do you think that I need to redraw the Network with "none" set as the surface from the get go?

No, have you ran an audit on the drawing? It sounds like you might have an error within the drawing.

Just ran an audit...still not working?

Try swapping the pipe with a very small diameter as a check. If you can then hold the desired rim elevation the pipe is too large for the structure and it is poping above the surface.

Changeing the Pipe diameters didn't work?

Can you post a dwg?

The most likely scenario is that the elevation that you entered as a RIM elevation is lower than the sum of the distance between the Rim and Invert.  (Top of Pipe + Barrel Pipe Clearance + Cone/Slab + Frame Height).

I would suggest a different structure that has a smaller frame.

Anytime I've had this problem it was because of the pipe size and/or invert in relation to the structure (or possible any structure "rules"), not really the surface. As a check try entering a much higher rim elev than it's defaulting to. If it sticks then it has to do with the pipe/structure as mentioned. It's telling you the structure can not be made with that combination of rim, invert, and pipe size.

That was the problem...

I just went into the Parts Builder and put a smaller size into the list for the Cone Height and now it works fine.

Thanks for the help!
