need to convert spline to arcs and lines in solidworks

Polyline edit command

I laughed at that a little, I remember how much typing of commands Autocad required and how much typing I use for placing lines arcs etc. I do not miss that at all.

As far as the OP I deal with this on a pretty regular basis and have had the same types of conversations both with customers and the owner here.

The preservation of geometry is critical, however you are still going to be guessing and fitting no matter the process used a mistake could happen. Programming could certainly piece together a program file running in line to process this profile. It is common for us to do that because of the same issue you are having with memory. Our programmers would break this profile into several sub programs if needed to keep the memory to what we have available for transfer.

I do feel for you on the front of being given a task that is overloaded on the front end with expectations of things that are accomplished in much more effecient ways. I don't use a hammer to put a screw in.(Well ok I did once, but that is another story.) Truly if you are stuck doing it this way, leave the original sketch unchanged. Create another sketch over the top of it and fit your arcs and lines to points that make sense and fit the geometry the best you can.. This way you will have an overlay at the very least if there is a question about the geometry you created vs. what was there.  Just from the way you have stated how the criteria for this project is  I would CYA as much as you can. This is why I am suggesting leaving the original sketch in your model untouched. I would also window the sketch and fix the damn thing to keep it from whoops changing.

Hope some of that is of use to you. Good luck.

Hello Mike,.. btw,.. what Dennis is showing is Draftsight (from the same people as SolidWorks),.. it is Free to everyone.

I am mandated to do this in solidworks only by my manager.

I am not allowed at anytime to download and install programs on company computers. (i thought i stated that clearly - read original post)

And this company does not want to spend any money on new software.

I think I worked for this company. They gave me a spoon to dig holes where most people were using a shovel, and then complained I wasn't digging fast enough.

Working smarter is sometimes moving on to work for smarter people, or perhaps for yourself.

Hi Mike,,, An update to this. Figured I had better test these macros on your file so you don't go pulling your hair out. I tried both of the macros that I had mentioned and each one failed on this particular file.. Here is another that worked. I did a Fit spline on the two splines (with delete option) first. Close the sketch then with the mouse pointer select the continuous spline in the graphics area prior to running the macro. I had done this in my first answer using DraftSite (Pedit) since I know from experience that this method has never failed me and as Paul Salvador mentioned it is free.. And as Chris Dordoni said it can go hand in hand with SW.. Just another tool to make life easier.

Note that this macro is named aa not aaa..

I just want to point out to the OP that converting spline to line and arc is an estimation of the original profile.

His boss maybe thinking it will be 100% by converting from Solidworks.

We all know there are tolerance but sounds like his boss got none.
