Smooth material removal

3D Design Volume Model
1

Hello everyone,

I need your help for a smoothed material removal with a specific shape at the base and then circular at the end.
How can I get perfect edges? Do you have a technique?
In my case I move the guide visibly but I would like it to be symmetrical.
I am enclosing my piece so that you can see.

Thank you for your help

Hello

Sorry but you have a more recent version, so you don't have access to the creation tree.
On the other hand, I see the play.

For me, apart from a 3d or lost-wax print, I don't see how you can manage the vacuum on your conical part.
Isn't there a way to extend the rectangular part on your cone and then take a leave?

Kind regards

Yes I think it's the best solution :wink:
I tried to make it too complicated :stuck_out_tongue:

Thank you for the walkthrough!!

Here is an example of a modification, after I don't know the purpose of this piece.

Thank you that's what I did :wink:
The goal is for the cone to guide to the drilling while keeping the grooves.

Many thanks

Hello;
I agree with @FUZ3D on the overall geometry.
On the other hand, in relation to your first question, you should use guide curves (3D sketch) between the two sketches of your smoothed material removal.

So, wouldn't it be easier to slope from the top towards the entrance of the drilling rather than making an entrance chamfer followed by a large wall like that?
Above all, that it risks a molded part right? it will be so requested by the mold maker to do the unmolding :slight_smile:

yes it's not stupid :wink: I'm also going to try even if it will only be for 3D printing.

Thank you in any case :+1:
