Need help in determining curved surface for the plate

[randyDDYWA]

Hello, a very small problem but a problem nonetheless. I have made these two plates and they are welded together. Just look at the dwg file attached. The part labelled "typical plate" has to be placed in an angle in the two plates there, refer to the assembly attached. When I try to constrain the small plate to the big plate, it shows error as the contour isnt right. Could anyone show me how to find out the contour when there is angular variation in the curved surface to be mated with. I hope the explaination was ample.

Hi @randyDDYWA 

As a general rule, structure geometries must be defined before welding.
It's true in the real world, and it's true in Inventor.

If you want to submit an Inventor project for review, you must package the entire project. The assembly file itself has no value.

 No parts (*.ipt files)?

Sorry. The ipt files are attached herewith

Here is the ipt files

That's all I've been able to position. The fact that the radius of the large slabs and the radius of contact of the small slab are not the same does not help with assembly.

Looking at the part, the way I'd approach this is to Derive the rolled plate into the stiffener part.

Then delete the edge surfaces.

Then use the face to cut the stiffener part.

You can use Split & Thicken>Subtract to get a good flat pattern.

You just need to remember to cut on the short side of the part to get the correct result.

Maybe someone else can do it easier w/newer versions of Inventor?

UPDATE:

Find attached an example of one of the many ways it can be done.

Using Split + Thicken>Subtract is one of my favorite ways to get a hole in a tank shell so the nozzle fits into the hole w/a relatively even offset to the hole for welding. I learned this method many years ago from someone in here.

My client figured it out. Thanks for the efforts though guys. As always, much appreciated

Hi! I believe this can be done using cylindrical face mate. Mate -> hover to the large cylindrical face -> right-click -> Select Other ->pick the cylindrical face -> pick the cylindrical face from the small plate. The angular constraint may not make sense now.

Many thanks!
