Model States and Sheet Metal

[johnster100]

Hi,

I'm makin a very simple model of a cone. I want two model states. One which has a split so i can get the flat pattern. one which is the just the solid cone (this will be used in an assembly model). The issue is i get a red cross and an error message when I switch to the solid cone model model state (primary state in the example model).

How should this be handled? ( we have a lot of parts which are rolled then welded). 

I've attached a simple file showin the issue,

thanks,

John

Hi

You can work around this by deleting the flat pattern and creating a model state with Rip and Unfold.

However, in my experience, I do not consider your workflow to be healthy, for many reasons:

1. The interrupt should be performed with the Rip function, not the Extrude function. When designing sheet metal, do not use solid modeling tools unless necessary
2. I also don't understand the need for a full cone. What is his role? What is it necessary for? What hinders the natural geometry of rolled sheet metal?

Hi,

I agree the rip and unfold is a bad workflow.

We like the full cone for higher level assembly drawings so that there are not extra lines on the drawing which will not be there in reality (the cone will be welded at the seam to make a solid cone).

I'm guessing what I want cannot be achieved?

thanks,

John

Hi! There is a hack to do that. Simply right-click on Flat Pattern node in the browser -> check Defer Update (also in Tools -> Doc Setting -> Modeling). The Flat Pattern will not update according to the folded model. Switching between Model States (ripped or not ripped) will not yield the warning message.

If you need to update the Flat Pattern, activate the ripped Model State -> uncheck FP Defer Update -> check FP Defer Update.

Many thanks!
