I am trying to make this 3D Path Sweep Cut but i'm getting self intersecting geometry. Would more guide curves help take this our or would loft cutting be better?
How will you be making the cut on the actual part? Is the profile sketch a ball nose endmill that will be used in a CNC milling machine?
Well…we’ll actually be 3D printing this hose nest so it won’t bemachined…if we were cutting it then yes the profile would represent the ballend mill.
There is one area where the vertical parts of the cut self-intersect. If you do the cut-sweep as a "circular profile" cut-sweep, it works.
...but the highlighted surface is where the verticals self-insect.
I created a silhouette split in the problem area...
When we look straight down from the top and zoom in, we see the problem...
yes...that's where the self intersect is...but is there a way to make the cut as if it were a Ball End Mill cutting through the piece what wouldn't self intersect?
Normally, you could use the "revolve" to create a sold body out of the sketch you created to use as the cut profile and then use the "solid profile" option in cut-sweep to have Solidworks do exactly what you are asking. But unfortunately, in your case even that does not work.
yes...i tried that approach also but with the same results.
It took some...creative modeling...but I was at least able to get this...
Thanks for the help guys...u all rock
As Doug has shown... a sketch circle has no problem.. but this will not solve because of tracking upwards at that radius approx mid way.. .. if that path is important.. then I'd suggest exporting the path as a surface and use that as your cutting path reference.
One trick you can use instead of a sweep, is to make a solid body of the end of the drill, like Doug S has a picture of. But then pattern that body using a the curve driven pattern tool. This will give you a bunch of bodies that you can then use to cut the other part using the combine tool.
A little resource heavy on your hardware, but it should let you make the cut your having trouble without overlapping geometry.
