Keep mirror while supressing base solid?

Daan_M — Mon, 06 Apr 2020 09:14:34 GMT

Hi forum,

So i created a iPart of a gearbox with a flange that can be mounted on either the left- or righthand side.

I created the flange as solid with some revolve/extrusions, then mirrored it around the gearbox midplane, see the result;

I want to be able to supress either of the flanges sperately. When i supress the original solid, it supresses the mirror automatically aswell. Any simple workaround to solve this? Thanks

Mirroring or Derived Mirror?

I don't know the difference between those, i used the normal 'mirror' function, the one in the 'pattern' tab

Can you share the part?

Wondering if you "pattern" it and make it independent if that would be better

There is something in the beta that would be great for this ...

I would also look at making this a derived mirrored part.

So you could have a standard modeled with it say on the Right Hand side. Then make a Mirrored - Derived Left hand version.

Whatever you do to the right hand (updating) it would do to the left hand.

I can share the file with you, but i rather not post it openly on the forum. Is there any way i can send it to you?

I can't add the file in pm so i've added it here instead. Its a bit chaotic but thats because i have to create a iPart with over 500 variats with flanges/shafts/shrinkdisks/sizes etc. I'm also a student, still learning about Inventor.

The problem as described is in solid 'flenssolid', i mirrored the entire solid to the other side of the gearbox. I want to be able to supress these solids independantly from eachother. Sometimes i need the flange on the right side, sometimes the left side. When i supress 'flenssolid' right now, the other side also gets supressed.

Thanks

So I would would do something like this

I think i forgot to explain a bit of the context;

I'm working on a configurator, where i combine iParts of a gearbox variant with a electric motor variant using iLogic code.

Therefore i find it important to keep all variants of this gearbox inside one file. I assume based on the footage that the method you showed creates a seperate file. Is there another solution? What i would like is just 2 seperate features in my tree, which i can supress in my iPart table. so basically;

member, column1, column2

Gearbox variant left, Left extrusion=1, right extrusion=0

Gearbox variant right, Left extrusion=0, right extrusion=1

Because what happens now if Left extrusion=0, right extrusion automatically turns to 0 aswell.

i appreciate the time youre taking to help out, the recording makes it easy to understand.

Hi Daan,

In case nobody mentioned it, there is an option in Mirror command, "Remove Original." You need to check it when you create the Mirror feature. Delete it and recreate it with the option checked.

Many thanks!

It's not the most optimal solution in my opinion but i suppose if it works it works.

While using the 'remove original' option i can supress the following way, assuming the left side is the original

Member, column 1, column 2

Leftsideflange, leftsideextrusion=1, mirrorofleftsidextrusion=Supress,

Rightsideflange, leftsideextrusion=1, mirrorofleftsidextrusion=1,

It feels a bit strange that i have to enable both to only get the resulting mirror, but it works....

Thanks

Hi Daan, the reason for this is that parts are history-based models. Without "leftsideextrusion", "mirrorofleftsidextrusion" has nothing to mirror. It's similar to if you put a fillet on leftsideextrusion. It wouldn't make any sense to suppress "leftsideextrusion" but want to keep the fillet, because without leftsideextrusion, the fillet wouldn't have any meaning. It can't exist on its own. The same is true for the mirror.

Hope that helps it make a bit more sense.
