i am learning how to use inventor while creating a new lamp shade. I am having issues with the loft function and would like to be able to create a loft with a constant 3mm thckness.
i have attached my latest file. Sone curves are 0.3mm thick. Anyone would have a tip how i could make this constant 3mm thick?
I am going crazy after many many nights on this projects! thanks for your help
I'll have a look, after you re-submit that part for the EOP marker rolled up to under the Origin folder.
Without trying it myself, my first guess would be to create your loft as a surface (lofting only the outside profile, for instance), then Offset/Thicken surface by 3 mm. I'm not sure how the Thicken operation will go with your sharp corners, though.
But, you've also got quite a mess in your sketches-- overlapping arcs, unconstrained sketches... how did you create these? Imported from AutoCAD? The sketches all need to be completely dimensioned and constrained.
I'd also strongly recommend modeling half and then mirroring-- it's far less work in this case, and will probably speed things up a lot.
You definitely didn't start with the easy stuff, did you? But it's a pretty cool model, just needs some work to get it done properly.

still waiting for a foreshortened radius dimensioning tool in Drawing Manager
Loft has a few limitations, especially when going from round to square, etc. I have had lofts refuse to work until I put slight radius' on the square (sharp) corners, then deleted them on the 3d model with delete face and heal. Instead of lofting as a solid you might loft as surfaces and then thincken them and combine them into one solid. A screen shot for those of us with 2011 would help. Have done alot of lofting as used to make dams, tunnels, bridges, etc, so if could see what you want might be able to make a better suggestion.
Guys, that is a brilliant idea! lofting a surface and then applying a thickness! thanks! I can t believe that i didn t founded that myself. I am trying to learn on my own and via this forum and youtube tutorials. i will try all this tonight! thanks again!
