Can anyone help me?
I am trying to straighten some RSA that I have drawn as rolled to enable it to be laser cut as a straight length then rolled to a set Ø.
Please see attached part and if anyone can help please advise.
Don't see anything attached.
Do you know how I could add an attachment now? I'm sure that I added it initially.
You can edit the original post (click on edit on right side) and then you can see the option to attach.
I can see the attached part in your reply now. You may try flex feature to straighten it.
If you're are looking to make it out of straight sheet, then model it as sheet metal.
I am not trying to make it of sheet - this will be RSA that will need to be laser cut in a straight length and then rolled / formed to a given radius.
I have had to draw it as already rolled / formed to get my hole placement and show as a model to a client.
you have mentioned flex feature - do you have any tips on how I could use this to achieve a straight length?
Will the holes be drilled before or after rolling?
For rolling, wouldn't the straight length need to be longer than the final curved length?
If you really need to show a straight length for laser cutting, use configurations.
I shall be putting the holes in after too avoid kinking, also for rolling I will be allowing 200mm either side - the lasering is to cut one side down and etch hole positions and angles for cuts etc.
how would you advise using configurations?
Within the same part, create a second body which is the longer, straight version. One config' would display the rolled version and the other the straight version.
Obviously you will have to calculate the hole positions for the straight config.
It might not be easy to straighten with flex, so try bending the straight profile with Flex. But either way there are good chances of distortion in the holes.
I can't open your file but here is what i would do.
Draw your angle in the rolled shape. Create a multi-body sheetmetal part and transfer the holes. Then just create a flat view of the sheet strip.
Make a configuration for the rolled angle only and one for the sheetmetal and use accordingly in your drawing.
You can also design it as a sheetmetal and then model in the sharp edges that you would have on a regular angle iron at the heel part. Again work with configs to represent drawing and real part.
You will need to adjust your k-factor to suit the rolled angle (trial & error). The question remains if your holes will end up where you want them. You will only know after you formed it.
