Lofting a rectangle into a complex solid shape.

[Anonymous]

I've extracted out into polylines the troubled area. I would like to loft the green rectangle up the z axis with the three blue polylines as a guide into a solid model. The idea I have is to fill the empty corner area with a solid model. Essentially I have extracted the edges of the solid model into the blue, yellow and green wireframe.

I have tried using the loft command however I keep recieveing the "at least two profiles must be selected" error message from the command. Is it possible to do this?

Thank You!

If this is a miter corner, do a slice 3 points or other options in SLICE maybe easier.

I haven't figured out how to edit image files in AutoCAD, but I am pretty good at editing *.dwg files.  Can you attach actual *.dwg file here?

Yes of course thank you for inquiring. A link to the actual drawing file:

I think the slice looks like a really good option.

Thank You!

I requested that you attach the file here.  I do not go to 3rd party drop boxes.  I keep my machine clean and never experience the problems that are commonly reported here.

I have enough flu shots, so I got this for you.

Maybe I missed the design intent - but this looked like 4 simple presspull or extrusion and subtract to me?

I've got an alternate solution for you - please see attached:

Draw 2 rectangles as desired.  Using the Loft command, select them and hit enter. You'll see a blue trangular grip.Click on it and pick "normal to end section". and voila. You can then use Presspull to extend the bottom.

I think Patchy and JD provided an easier method to reach the intended result,  but to answer the original question about Lofting to a Point with Guides, you select the profile (green rectangle) then use the [P]oint option, followed by the [G]uide option.

Another option, provided those are simple radii, would be to union the two square bodies, then do a chain fillet. Of course you would need both bodies to extend beyond the fillet dia. then Press Pull the extended parts.

After trying a mocked up version you don't need the smaller bodies to extend past a full fillet radius, just to be equal. Also it seemed the chain option only got through 2 edges whereas the loop option got them all.

cool tricks, there are so many ways to do this in ACA, but i always say when trying to create a solid shape its best to create a solid and then subtract the desired curvature. then there's no converting later or complex manipulation you have to use. just created the same shape last night for a flare on a shingle style house. good luck!
