loft as a solid

There have been multiple threads that demonstrate that the loft feature is ignoring the Solid option, and in fact the dialogue box under settings is greyed out and not available.  I've been trying to do the same thing this week with no luck from any possible strategy. 

 

Attached is a screen shot of the settings option that is unavailable to generate solid.  You can see the chamber in the background that I've been trying to fill multiple ways, with no success, for a fluid modeling application.

 

Has this issue been fixed by now, and if not, what are my options?  Thank you!

Can you save the .dwg to 2007 format and attach it here?

Sure.  It is attached.

It was drawn in ISOMETRIC mode, the shape is actually a rectangle in PLAN view and the vertices are overlapping so you can't LOFT.

You are saying that it should have been drawing differently, and if so, then how?   I see what you are saying, but I didn't realize that you could not loft to the same shape, that it had to be generated via 'non-overlapping shapes.

 

How then, at this point, to make it solid?  Sweep doesn't work either.  Can I make it loft the other direction then, with some modifications?

Thanks -

I would add that we've tried pulling the file into Workbench (ANSYS) and can't fill it either.

List the dimensions and draw it correctly on World UCS and LOFT.

Tried lofting the other direction, with all horizontal boundaries removed, and it says that the output body self intersects. You would think it would work horizontally, since there is a slope on the bottom surface, and therefore the profiles are not identical.

Can you send this as an attachment? I can't see closely enough to confirm whether there is a chamfered edge on the side closest to the two incoming channels. Can you also send a link explaining why it made a difference to construct it in World UCS vs Isometric?

Isometric is just a fake, it has same Z value, therefore two shapes can't be LOFTED.

I started out in world UCS, but moved around to construct. Not sure how I would have done that differently, but thanks.

I'm still getting the same result!

SNAPSTYL , Use 0, get out of Isometric and start using the Viewcube (or anything you draw can't be LOFTED)

Was pulled for a meeting.  Can you please explain what you mean by "drawing correctly in World UCS"?  I tried to copy the same form after changing to World UCS. That just lofted again.  Why does this not work?

Attach your latest .dwg (in 2007)

and let's see your progress. It's easier than guessing It Doesn't Work

Here you go.  Not fully redrawn.

It would be a miracle this shape can be constructed in the field, all surfaces and no thickness.

It's already built!  So how did you do this?

 

We're just modeling it now to troubleshoot grit settling at low flows on the side of the chamber opposite the exit pipe.  The two channels replaced old brick sewers to work around existing conditions, in changes to I-95 passing through Philadelphia.  We'll probably be removing some depth at that corner to mitigate the problem.

 

Thanks a million however.

The file is constructed as it is to import into ANSYS fluid modeling, not for construction.
