Help with sheetmetal pattern rotation

[PaulProe]

I am working on a sheetmetal part that has multiple angles, which forces the flat pattern to skew (rotate)

In my drawing, I want one edge to be horizontal so the dimensions can be used for layout rather than having to figure each and every point.

I can't figure out how to precisely rotate my flat pattern so I can make a named view to use in my drawing.

can anyone point me in the right direction. I've attached the part and when you project the flat pattern into a drawing, it is rotated a little more than 5 degrees



Thanks

Paul

Poul your fist flange is tilted !!

Hello Paul,

like this?

When I encounter this problem I will make a configuration with the part unbent using the unbend tool. Then create a Assembly, bring in that part with the correct configuration (unbent) then you can precisely place the part in space to best suit you needs. Then create a drawing of that Assembly to dimension.

Hello Paul,

in your sheetmetal part:
- edit sketch<1>
- reset view (orient the view to the normal of the current sketch)


- go to view and analysis tab

- mangage view orientations


- add a new view


- make the new drawing and click on workspace orientation


- choose your new created view




- place your view

- ready?

Stefan

Why not start with the first sketch (flange) laying flat.
The part you make can be placed as you want in your assembly.

Thanks, guys. Oldbelt, I design from the top down (Make the assembly and then add parts as needed). That ends up making many of the parts skewed.

IDSLK, used your tips to make the flats and it worked perfectly.

Alibre could really use a good manual (Max?)

Again, thanks

Paul

This works perfectly...I was trying to create a custom view but was trying to eyeball my part level but your first steps took care of that. Thank you for your tip.

I never do that. I've always found it works better in the long run (for me anyway) to design individual parts in their own part file, then bring them into the assembly & position as necessary.
