Does anyone know how to make a cylinder with cutouts and radii in solidworks?
The cylinder has radius corners and a pattern cut out of one of the edges.
I've tried the unfold feature but can't seem to fillet the corners and make changes to the edges. I've attached the flat pattern version dxf only. Probably a simple question for someone.
you could have used the fillet command to add the radii at the corners
works OK see attached
Attached file, just roll back the history tree, that the blue bar at the bottom of the feature tree to see how I did this.
file didnt seem to have been attached
I tried the fillet command on your file and it works OK, see attached.
just select the corner edge, email me your model and I will take a look.

Thanks for your help with this fillet thing. Your example is what I had managed to achieve using the unfold feature but I still couldn't get the fillet to be applied. I managed to get a result which probably could have been done in a better way.
I've attached your file with a modification. I did this with the extrude cut after doing a sketch. Probably not the right way.
PS I like the wrap feature you showed me.

Thanks John. I tried that but it wouldn't let me do it so I thought I'd extrude cut the pieces I didn't want. Long way round I think.
I'll send you the result soon. Took me a long time but I'm still learning.
Did you do that with the wrap feature? I did mine starting with an arc first on the sheet metal tab then used the unfold feature. I tried using the fillet command on the feature menu but didn't work. Must be doing something wrong.
Hmmm. I tried again but still no luck. I made an arc first, then unfold, then fillet edge (constant) but always says unable to make fillet. Not sure now. Thanks for your help though. Checked your snapshot and selected thse edges. Maybe I'm selecting the wrong edges? As far as I can see, all looks okay but obviously missing something.
Did you receive my email address? Would be interested in seeing the video you made with the fillets..
Hi, after i take a look on your dxf file, i just guest that you are trying to add fillet to a sheet metal, but in form of cylinder. please take a look at my file, maybe it can help you, i add the fillet after i use unfold features first, then i use extrude cut. Not using wrapping features. Also need to consider before extrude the cylinder is a miter gap on the sketch, make sure there is gap around 0.3mm, then extrude sheet metal can be use. Don't hesitate to download the file. Anyway, i'm using 2012 version, so i can't open newer version, or you can uload iges so i can check for you. Thanks,

just a few tips, a cylinder sheet metal is not same a bending sheet metal, because to use fillet, the surface or edges must be line, not polyline, and planar surface, not wobble surface, like cylinder, if we fillet it before unbend, hard to detect the edge or surface because it is not perpendicular like normal bending, only recognize on tanged edge. That's why i prefer to add fillet before apply the Fold features, because easy to detect planar surface. one more thing to consider is, line of sketch position, because need to use K-Factor bending. Let's say your sketch position is inner (as like what i do in the sample) K-Factor has to be 0 value, if line positioned in the middle of thickness, K-Factor value should be 0.5, and if line positioned outside the thickness, then your K-Factor value is 1. this value play main role to archive actual unfold size, if we put it wrongly, actual unfold size will get wrongly too, like over than 3mm or less than 3mm, in manufacturing 3mm is a big waste, because after cut the sheet, the sheet can't be used any more, it is not like 0.5mm, this consider as tolerance... :)
is it solve your problem?
Thanks for your answer. I had a look at your cylinder. the way you achieved this was the same way I did. I started with an arc, extruded the arc, then I did the unfold and extrude cut.
I've just found out though that you can apply the fillet in the folded view by picking on the point in the corner. Thanks for your help.
