how can i convert spline lines to arcs??
I would say - unfortunately you can't. At least not exact.
Arcs has uniform curvature by definition, and splines does not.
To do it you would need some approximation and as far as I know it is not possible by native SolidWorks. Perhaps macro or plug-in.
Meticulously creating arcs to overlay the spline. However, like Thomas Voetmann says, it won't be exact.
You can't do that, make some approximation with arcs and lines
Aside from tracing over with arcs manually in SolidWorks, there are several applications that have a function to do this automatically, including AutoCAD, Rhino, and TurboCAD.
AlphaCam is yet another platform that can do this, but my "premier" 3D software cannot. I would love to see this added in the near future. The CNC controller for our router will not recognize a spline, so I have to use arcs. This adds multiple steps that I am sure the software could do more accurately and faster than me. How can we get this looked at?
Good Question Berry... I haven't nc programmed for about 15 or so years now but the guys tell me that they are still using the same process that I taught them since they still have the same lasers, mills, and turret punch presses than when I left. EDIT:.. whether they still need to too is up in the air.. I'm sure their cad/cam software has changed but they have always had the capability to smooth entities . They are getting a new 3000 watt fiber laser and I expect there will be no issues with the new controller.. Don't know for sure yet.. I have noticed that with some of the newer (more resent) companies I have been working with splines don't seem to be a problem.. Of course the code is broken down into hundreds and hundreds of lines now.. Without what I call code.. Just movements..
It may not help, but I believe you can export splines as polylines, would that help you?
This is from the knowledge base: S-07805
Q: How are DWG files exported from SolidWorks? Splines are exported as poly lines and not splines. How can this be fixed?
A: When saving as DWG or DXF files, splines and arcs can be translated to polylines. This is dependant on the version selected under the options menu in the save as dialogue box.
To have splines appear in a DWG, choose file, save as, and then choose DWG from the pull-down menu. Now click “options.” In the version pull down box – select R2000-2002 or R2004-R2006. Click OK to accept the changes and save the DWG normally.
Check this out Jose... Both methods work but I usually use the export to dxf then the pedit method (with AutoCad or DraftSight). I started using that probably 20+ years ago but the macro works very well also.
Hi Jose, we usually use rhino works well. i use to use the sketch tool segment to give me a good approximation of how many arc and lines i could break into plus it gave me points to use three point arc on
