Cannot extrude between two circular surfaces, with minimum solution!

[janniandersen]

Hi Everyone

It seems to me that it is no longer possible to make an extrusion between two circular surfaces or solid bodies, and choosing minimum solution in both ends.

Is seems like the button for minimum solution on the first surface (Blue) disappear when selecting the second surface (Red)! And actually when selecting the first surface the result looks pretty strange.

I really hope some of you can explain this, because I do this kind of extrude every day and now in Inventor 2020 I have to use two extrusion features, instead of just one, as in Inventor 2019. 😞

Hello @janniandersen,

Look at below image and enclosed file for reference.

Hope it helps!

Hi Xun Zhang

Thanks for your answer, by studding your screenshot and model minutely, I finally found the problem.

Need I say I am not a big fan of the new property panel UI design.

Can you help how do i extrude BETWEEN 2 solids (not faces), ie I beams

thanks

Post your file, tell us what version of Inventor you're using, and include an image of the desired operation unless it's plain for all to see.

This is an just example of the type of extrude I want to do
I want to extrude between the 2 solids so the new part is profiled at ends to suit solids shape
This is just an example, so don't tell me to use frame generator.
Here's what I want, but not with 2 operations (extrusion 3 and 4) to make the 3rd part

Based on your description, are you looking at something like this?

Then with extrusions have it cope for you?

I just did an extrude to next and chose solid 1, that gave me the cope, then had to use the same sketch and extrude the opposite direction using to next to select the other solid, but using a join operation to join the 4th extrusion to the previous.

You could use frame generator and do this with 2 clicks and reuse that member as well lol....

Either way, you will have to do some coping. Even if you want perfect size on size, or you offset some surface for splitting cutting/or manually drawing a coping profile...

The Alternate solution button is what you want.  It cycles through the different valid solutions so you can choose the one that matches your intent.

Thanks, yes I'm aware of this.

I want to know how to do it as 2 clicks ... like we used to able to do with between by selecting both solids

[Teepee101]

thanks, but I was trying to get copes on two non-planer solids

[Teepee101]

I have attached the files in a post couple down, thanks

There is no option in the Extrude tool to extrude between two solid bodies, just between two faces.  That would be a sensible and useful enhancement, especially if it also included surface bodies as well.  A quick search in the Inventor Ideas forum did not show a request like this, so I encourage you to add it (and post a link in this topic so others can go add their votes).  I will certainly vote for it!

In older versions of inventor this was possible

[SBix26]

Which versions?

You can go "to next" which will terminate at the next solid, but it is only in 1 direction. Wish it would go both directions.

Yes , I must have been dreaming it (same dreams of custom pipe elbows for pipe falls....oh no wait... 15 years later...)

Adsk will not give us everything we ever need unfortunately. That's why we learn to model too lol.
