Hello
I have to model a rolled sheet metal made by crunching.
So I draw my profile with a polygon that I cut to form a semicircle.
The problem is that my semicircle is 215mm radius and I would like my folds to be about 10mm long.
I notice that the polygon function only accepts 40 sides no more.... I will need twice as much.
Do you have an idea?
Hi Bart, with a symmetry in the middle? That way you model your part and then you symmetrize it!
It's Aurelin sheet metal, so if I do a symmetry, the folds won't merge....
However, by doing symmetry on sheet metal, my piece is well merged me (and I'm in 2011. So you should have it too)
Thank you for your answers, but how do you manage to have several 10mm lines following a semicircle?
I can't read your play Remrem, I'm in 2014 version.
The problem I have is how to model these small 10mm lines following my arc
It's just the talent Bart
This is what I manage to get (see image)
I have 30mm folds with 20 strokes that I made with a polygon (Sw only takes 40 faces max)
I would like the same thing with 10mm folds and therefore more strokes.
@Coincoin: Can you get 40 veneers of 10mm?
@Remrem: I only count 20 facets on your piece... Your folds should not be 10mm
Hats off @remrem, simple, effective!
I don't know if @remrem'll come back so I'll answer you @Bart:
Look at the image of the transition crease feature. It's from 2015 like @remrem. Let's see if you have the same options for 2014.
Edit, the 2 sketches are identical, an arc of a circle of R=125mm (a single entity, not split)
I created a sketch on my front plane: a simple 215mm semicircle
Then I create a second sketch on an offset plane: identical to the first one by converting the entities
Finally, I use the transition crease function. This way you can adjust the parameters to get the number of segments you want
Why don't you make an arc of a circle at the right length, but in a construction line.
Then you glue a 10mm line in coincidence with the circle at each of its ends.
Then you do a circular repetition of a sketch of this line.
I will even add to complete @coin37coin that the angle of your portion should be 4.5° (180/40):)
I'm trying to make my most transition, but it's not working.
I followed Remrem's approach but it doesn't work (see image)
@Coincoin, that's what I want to do, but how do I get there?!
Be careful, my radius is 215 so diameter 430 ;)
For the transition plui, OK
But I can't adjust the length of the segment...
Do I have to look for it manually?
I can model my part by checking the "Rectilinear tolerance" box minimum 0.5mm but my folds are 28mm...
@Bart, you can't seem to click here:
[EDIT] Oops, I misread your penultimate post!
Bravo @ remrem
@+ ;-)
Yes, but when I enter my valuer, the function cannot be validated.
Have you tried my part with my settings?
Han this scam. You had sold me a dream with the transition fold.... but I don't have all your options with 2011:(
@Bart, that's a bit of a problem with my method. It's not innate. As @Aurelien pointed out, it will have to be calculated. :s
