Patch on angled stitching

3D Design
1

Hello

I'm looking to make a patch (reinforcement) on a penstock that arrives at an angle. I have already managed to make this kind of part but it was a gas plant and I would like to find a simple and relatively quick solution. What I would like is for the patch to follow the contour of my stitching. I don't know how to recover the curve properly.

And last thing, I'm trying to create the cut of the tap in the main pipe but I'd like to have a normal cut to the original pipe but it doesn't work. I did carry out normal removal but it doesn't change my problem

I enclose my piece to you; I'm in SW 2019.

Have a nice day

an image would be preferable we don't all have the same SW version

or the parasolid file

Correct. Here it is in parasolid

Hello @pthuillier

I don't know if I understood what you want.

If your goal is to pierce the Patch in accordance with your stitching, you just have to move your Patch above the Extru2 removal :

Then edit the Extru2 removal parameters to add the Patch as an area of action :

Kind regards

No, that's not it, I'm looking to have a normal material removal from the main pipe. As if I were cutting the pipe with plasma while remaining perpendicular all the time. Otherwise it makes me an extrusion like this and it's not representative (see attached image)

And for the patch I try to make it fit the shape of my folded sheet metal stitching which I can't do

Hello

For the stitching on the same diameter , I proceed as on the test in pj. I do it regularly as soon as I send it for laser cutting, and it's perfect! For a smaller diameter, we are not faced with the problem. For the patch, I've never done that. Can be surfaced, offset surface!

Kind regards.

Hello

Thank you for your answer, unfortunately I didn't answer earlier, partial unemployment has been there.

It's almost that @contact_168 but I still have the cutout on my tube that doesn't fit the way I want, it's not normal to the main tube.

A blessing in disguise this partial unemployment because by coming back with fresh ideas I managed to get what I wanted.

I'm attaching a little part for you to visualize.

And what I get on my main tube

I hope it will be useful to some

The solution to have a cut corresponds to what is done on a laser (or plasma) cut on an axial welding robot is to do the following steps:

-projection of the inner diameter of the intersecting tube onto the tube to be cut using the Curve / Parting Line tool: this defines the outer contour of your cut on the part to be cut

- make a stitched surface of the area to be removed

- take the surface to be removed and do a thicken function (thick enough to remove the entire thickness of the tube)

-> You have your pretty cutout

You can do the same kind of trick to draw the horse saddle (the external reinforcement to your tube): you draw a tube on the outside of your main tube and you remove material with the method above for the inside and outside.

Nb:  if you want to unfold it you will have to make a small piece of dish a priori

I didn't see that you had solved your problem.

You do have the "thicken surface" but it's very complicated before. My solution is much faster to do.
