FilletEdge simple shape fails why?

Hi, V5
also V7
FilletEdge fails on the outer edge of this object,
Needs to be 0.025

shape is an exact recreation of the item, with drawn radiused corners then curve extruded, then I need to FilletEdge the ends.

but it fails.

Hello - where fillets collide, and they are the same radius, do them all at once.

Hi,
the edges were pre drawn, with one needing to be 0.04inch. then extruded.
How do I approach the fact that they differ and are not all 0.025 ?

It might have been these were 0.03 with an 0.04, then the ends 0.02

Steve

Hi Steve - you need to organize things so that the larger radii are done first, or you can mix and match fillet radii in the same run of the command. You cannot wrap a new fillet around an existing fillet of the same or smaller radius after the fact.

Hi Pascal
I didnt realise one could enter differing radii in the single command.
So rather than draw the four corners and extrude, do it as a box in side view, projecting the lines out to form the corners, then use filletEdge to achieve all edges, and using the next radius command to enter a different radius.

In the one command for this, you are saying enter the larger radii first., so anything with multiple fillets plan it carefully, larger fillets then smaller ones, all in the one command.

I will try for that.

It had been that I was going to draw without radii, then fancied making it a little more real and established the radii for the end view and extruded it, then fancied filleting what remained as well.

…and it worked…many thanks.

Cheers

Hi,
and then I try for this one, one radii this time, looks simple enough, but it fails.

again I dont know why. is there a curve radius fillet falls over at ?

0.01 works
0.02 fails

Steve

As mentioned, a few times perhaps by now: You cannot wrap a fillet arounnd an existing fillet, or edge, that has the same or lower radius.

Hi,
Must have forgot that, though not sure where that was. However now imprinted in my head :slight_smile:

I will have to alter items true shape to suit the fillet. I had simply traced the item and could see it had filleted edges.

Does this mean to say that its impossible for an engineer to make it then fillet with file or whatever that fillet in that area ?

redone with 0.025 then 0.019 then 0.025 and bingo, a fillet :slight_smile:

Steve

Hello- well, a true rolling ball at .025 will not fit in there, if that is the question - you can increase the radius on the base part, or make a non-rolling ball surface in that area.

Thanks,
its the bend at the side that sees the fillet crease, and thus fail, so manual edit it or go for a smaller fillet rad just there.
