i have designed a plate that has a couple of holes in it. The plate will be first laser cut and then bent to a specific radius before installation. the plate basically acts as a spacer.
the problem is that i have to work with an older version of proe (wf3) and there are problems when bending the plate - centerlines of the holes stay where they were from the start, they do not bend with the model (see pic).
Thus i am not able to create a functional drawing, because i also have to also dimension the approx. angles between the holes. I would also like to have centerlines shown properly, because the drawing itself is more readable (the part is quite big and thin).
I need to have a plane across the first hole (with bend center as an axis - View A in the pic) so that i can also create a cross section view for the drawing. That also doesn't work.
any idea how can i accomplish that? I would like to avoid modelling it in a newer CAD, because i have to include it in an asm and mate some other components to it (the holes), which would be difficult with a STEP.
Wildfire 3, release something above 200.
thanks for any feedback.
Usually when I make a drawing of a part that was machined in the flat state and subsequently bent, the flat pattern dimensions are enough to define it properly. However, on those occasions where I need angular dimensions in the bent part, I resort to the following (for the part after the bend):
(1) Make an axis at the center of the part.
(2) Make angular offset planes through the center axis, one for each hole that needs a dimension.
(3) Use relations to define the angles. For most cases, I already know the angles of the holes, and used them to calculate the linear positions in the flat pattern. Thus, this is generally a simple "anglePlane = angleHole" equation.
(4) Now, you have nicely positioned planes that you can use for dimensions in the drawing.
If you need axes at the bent hole positions, you could take the further steps of creating them as intersections of the planes above and a plane through the holes that is perpendicular to the axis of the bend, but you don't need axes to create dimensions.
As for a plane for a cross section, just make that through the axis of the hole(s) prior to the bend feature.
A caveat, I can't even remember how far back we were using WF3, but I think all these things should work.
Hi, I would be tempted to model the component as you need it in the final installed condition rather than you attempting to fabricate from the flat. I did a quick model and extruded a plate that looks very similar I added an axis on the cl of the plate and did a radial hole that I then was able to pattern. When I flat pattern the part the axis is on the holes and it is also there in the design state.
