Why does frame generator not follow parameter driven skeleton?

[mwesse]

Hi All

I have a simple rectangular frame that is fully parametric...acting as a skeleton for frame generator. I modified the cross member count from 5 down to 4. All the sizing has responded correctly but it has left an orphan frame member...any ideas? 

I have had about 20 years experience with programming parametric parts in Archicad...its pretty tough crossing over...parameter driven construction shouldnt be this hard???

Hi! There should be a logical reason to the behavior. Could you share the files (iam and ipt) here? Forum experts could take a look.

Many thanks!

Hi John

Here are the basic files...so Im just modifying the NumOfUnits parameter would should add/subract dividers in the frame.

Hi @mwesse,

This is a sketch pattern case, which means you edit the pattern number (add/remove), you have to edit frame member again to re-select the addition frame line or delete the useless frame. The reason is the 3D sketch "Frame reference model" do not know the change from your skeleton with pattern number change, you have to manually fix it.

Refer more from below video.

Thanks!

Yes but why cant the skeleton members be tagged so the frame gen know what is meant to be applied rather than an meaningless internal id?

More importantly, how does one create truly, fully parametric objects in inventor?

Does that mean Im better off not using the frame generator but rather doing all the work using parametric evaluation in the pattern generation of the part modelling?

I tried mirroring etc some sketch parameters for a reasonably complex extrusion and it brought my fairly powerful PC to a standstill so I have given up doing that. Revit doing do it very well either but Archicad did it effortlessly...but its not exactly an engineering package 🙂

Hi @mwesse,

Yes, it seems a gap here and it's a good enhancement candidate for us. Would you mind nominate a new idea to ideastation to track it down?

Thanks!

Hello @mwesse there are a few ways to accomplish what you want but the best I would imagine is to incorporate iLogic. 

Check out this great assortment of models and see if you can use some of the methods presented.
