Is it normal to have to put my crease ribs back on when changing thickness?

 

Has this ever happened to you?

How do you make your folds? Folds on edges?

@ Bart how do you go about creating your piece?

This may help you understand why you are re-rating

Yes, edge folds.

 

For example, a 600x400 4-ply cover with 4 60mm peripheral ply

 

If my sheet metal is 2mm and I pass it in 3mm, my folds increase by 1.5mm and are therefore 61.5mm

 

Every time I change the thickness, I have to do all the functions to check the ribs.

Here is my piece. (In SW 2014)

An image for those who are not in SW14 STP?

I don't remember having any problems with that. Did it do it to you all the time?

Here is the screen print.

 

Left image 1.5mm thick.

Right image 3mm thick.

 

We can see that the 21mm fold turns into 22.5mm

Use the circled option, it will save you from having to adjust your dimension according to the thickness. No?

Yes, I know that's not the original question... :)

if you do sheet metal and your plies are inside (position of the folded sheet)

you should keep the original rib even if you change your thickness

See my attached file

In fact, it all depends on how you measure the height of your fold.

The option you clicked, virtual intersection exterior, allows you (theoretically) to have a fixed height outdoors.

The other option (favoured by Benoit.LF) allows you to keep the same length off the shelf.

 

Then you also have the bent sheet metal position that comes into play. Anyway, given your options, if you do an outside side shot, it shouldn't theoretically move ... unless you have created equations?

And you're the one who crosses the hill the pitch 21 at 22.5? Because if it's not the case, it strongly encourages me to think about automatic equations/relations

Hi Bart,

I made a sheet metal part, and the bend lengths do not vary according to the thickness.

As coin37coin said, it makes you think of automatic relations/equations.

I advise you to recreate your piece from scratch to see if you still have the same phenomenon.

Enclosed is my sheet metal part.

A+

No, but I've been drawing sheet metal for 3 years.

 

I encounter this problem from time to time, but I don't know why...

 

In most cases, everything is going normally. But sometimes it gives me that, and unless I redraw the room, nothing changes....

It's Solidworks that changes the rib, I only change the thickness!

 

However, it's a fold with an external intersection, so logically, no worries.

And by ticking the option indicated?

No benign, the option puts my fold inside...

If it only does it from time to time, it's not normal.

Maybe an old automatic relationship that  drags on and makes a mess.....

Hey, it's funny we come back to the question of @Alain (http://www.lynkoa.com/forum/mise-en-plan/cotation-des-mep-par-objet-du-modele-solidworks)

Is it really annoying that the listing is indoors? On your 2D plan you will place a dimension outside! No?

I modified your folds on edge 3, I put a 0.1mm offset. And when I change thickness, the crease dimensions remain at 60mm.
