Adaptive sheet metal flange

[Anonymous]

How can "or can you ?" make a sheet metal flange adaptive? I’m using Inventor 5 I really only want the angle to be adaptive. I don't care about the length of the flange changing. Example....If I had a box 24" X 24"....all six sides equal....the four sides that surround it are 1/8" thick sheets..(No flanges)...the other two are the front and the rear of the box....the front being side 1 and the rear being side 2.....These have flanges all around them 1" long at 90 degrees......if I take side 1 and make it 12" X 12" then when I update everything after editing Side 1 the angles of flanges on Sides 1 and 2 should change but instead after editing it gives the big "no can do" constraint error message.....Now....my drawing consists of six parts… Side 1 through Side 6 and there all adaptive from the ground up!! Is there something I'm doing wrong or can this even be done?? Anyone’s help would be greatly appreciated. I will try and attach my sample drawing under the same heading to CF for anyone to Dissect…. Thanks Gary

When you change from 24" to 12" you want these 1" flanges to angle out to the 24" size???
Or is what you are wanting to have the other 5 sides scale down to match it?

A couple of starter points on your drawing... one part should always be grounded, and the
part you are changing shouldn't need to be adaptive.

I prefer the master sketch method personally. Unfortunately I think the tutorial on my
site was done in R5.3

Yes... and vise-versa for the 24" side "side 2" which will have it's angle's go inwards to the 12 X 12 side. Note...all six sides will change making a pyramid shape with the top cut off... If you notice in my drawing that side's 1 and 2 have flanges with "corner seams" to allow for this change in angles. With out this it definitely will not work.

Question??... If I had a sheet metal piece with one edge only having a flange…and I drew a sketch through it….and I constrained the sketch to the sheet metal ....could I drive the angle of the flange by changing the angle of the sketch....flange being adaptive of course.

Unfortunately I have no way of posting anything in R5 format. I would still suggest
looking into Master sketch modeling of one sort or another. There are tutorials at a
number of places
I have on one my site, but you won't be able to open the file, only read the PDF that goes
with it.
http://www.mymcad.com/KWiK/mcad.htm follow the iMaster Link
Sean has one also www.sdotson.com and you can find one here (watch for word wrap)

As for your question, I think you would have more luck using a contour flange than a
normal flange. I have personally found adaptivity to touchy and don't use it much, so I
am probably not the best one to answer your questions on it.
