Editing Curved stock of sheetmetal

[Guest jkim522093]

In sheetmetal, we could edit the profile of curved stock using

line drawing tool at the edit crossection. But when we draw the

circle and trim it to make the profile, then circle disappeared.

But the other curve and lines has no problem.

Kim I don't understand what the issue is completely. Could you try re-wording? I understand that you are attempting to edit curved stock to add a piece of a circle but that's as far as I get

The problem is that the remained circle is not displayed at all.

For example, drag & drop the curved stock from the sheetmetal catalog,

and then select the Edit Cross section. And then draw the circle(any circle;

center radius, 2 points,...) as the above fig.

And then clcik the Trim curve icon at bottom, and click 3 of the above fig to

trim off that part of circle.

Then the remained part of the circle(number 2 in above fig) is disappeared.

But if we move the mouse to this part, then we could see that this remained

part(2) is still there but not displayed.

(If I use the curve or arc instead of circle, then the remained part of these

curve and arc are displayed after the trim off. So I could see if the cross

section is correct or not before to click finish.)

 

The problem I pointed is that the remained part of the circle after trim off

should be displayed.

For your reference, even though the remained part of the circle after trim off

is not displayed, it is still there. So if we click the finish button, then the

remained part of this circle became a crsoo section and visible.

I too experience the same, using IC 8.0, and also other problems with "curved stock".

The cut and extend tools are certainly not predictable for radie and circles.

Further, I tried to bevel off two sides of a curved stock using hole blocks. One side ended up correct, but the other hole block did not swing into the right position in the unfold position and hence did not cut as axpected. I get a feeling the two sides of the 2d sheet divided by the X- axis, are not connected or cooperating properly. (I think it's the X-, but could be the Y- axis).

I then tried to cut with a solid block using "cut sheetmetal part", and that gave a proper unfolded shape, but an unusable edge line on the flat shape in the drawing, that cannot be picked for dimensioning.

I also get a tilted display of the unfolded view when the radie crosses the 2d-sheet x-axis.

I'm trying to get a curved lexan windshield ready soon, but this is beginning to get very boring.

Also, there should be a way to edit the curved stock in the unfolded shape, and project this back to the curved shape, as this is how one cuts it, and a straight edge like it's cut or sawed, is easy enough to model on the unfolded shape, but tricky or impossible for IronCad on the curved shape.
