Unable to Combine two solid bodies Inventor Pro 2019

[Anonymous]

Hi  I have attached model. 'Solid 1' is Soild Output and 'Solid 2' is Surface output. If I give 0.5mm fillet between them then 'Combine' feature works (but that fillet looks different like negative radius)

As per my knowledge 'Combine' feature works without any relation between solids.

Thanks.

Something like the attached first attempt?

Hmm. In Juergen's input I only saw a tube with some holes, pointing to the center axis.

This problem can be worked around by deleting the contact faces of both solids, and doing a stitch operation after that.

2020 IPT attached.

🤔 But next problem will be shelling ..

Sorry. I posted the wrong file (**** Part1 name). 

Here the right attempt. 

You can still refine it adding tangent conditions at both sides.

Exactly the same was my first attempt. But I was not happy with the sharp edge (see  image). 

Therefore the next variant posted above. 

Here my final result (new day, new happiness) with tangential conditions AND an added shell.

Hi! Here is a solution without using Boundary Patch. The issue with BP is that the resultant face edges may not be precise (tolerance <= 0.01mm). This can cause some issue with downstream modeling, since Inventor is a precise modeler (3D geometry accurate up to 0.00001mm).

BP is best for covering an area or create a large surface as a base for further trimming. It should not be used as a replacement for Loft. Please take a look at the attached 2018 part. It looks like you are on 2018 RTM build. Please install 2018.3 update followed by 2018.3.9 update.

BTW, this is a symmetric model. You may want to model the half and the mirror at the end.

Many thanks!
