Leave material to trim

[steven.coxVCM6J]

Hi all,

The fabrication shop wants to leave rolled pieces long and trip them in place to allow for any rolling errors and inconsistencies.

In 2D we just show this as phantom lines...no big deal.

However, in Inventor, the part need to fit in the model without overlaps or interference.  How can I show the extra length on a drawing and still have the part be accurate.

I guess I could add the extra in a separate Model State and us that in the drawing.  Is there a work flow for this?

Thanks, Steven

Yes, model states is a good idea in my opinion.
If you create an additional model state for an oversize version, you can add material using Thicken.
When using Thicken you can check the New Body option - this way you will get a new body in your component.
This solution will allow you to easily change the line style for the allowance in the drawing.

You can also edit the flat pattern and add the material on the flanges you want.

That way it shows up on the flat pattern only and no on the formed part.

Thanks for the suggestion.  I like it and it's easy.

Thanks for the suggestions.  I will remember that.

That's how I've been doing it all these years without ModelStates.

There is also the option to edit the flat pattern of the parts to show it, this allows any external programs like Radan to grab the modified flat pattern but leaves the 3d model as you want it

So this is what I have done.

Created a part (flat bar).  Added the bend.  Then used thicken to add required trim allowances and set thicken to add a solid body.  This will allow me to put the finished part on a drawing using Model States.

I then used Make Part to create the "Flat Pattern" part.  In make part, the Derive style is solid body keep seams.  I can use this part to do the flat layout and show the raw part prior to trimming.

If I edit the original part, the changes update to the flat layout part so I do not need to edit two parts to accomplish all that I need.

Thanks for all the suggestions.

Just one part is the best way b/c it's easiest, like you say.

No back-tracking and loose-ends at the end of a project.

I've used Derive to bring the flatpattern into another s/m part and then add features, then use that as the f/p in the drg. There are better feature tools in the normal editor cp. to the s/m f/p editor. Only thing is, it's 2 parts instead of 1. But it auto-updates when changes occur to the Parent part.
