<div dir="ltr">Alan,<div> Many in the club use DesignSpark Mechanical or Fusion 360 for making 3D models. Both programs are free and can handle .step (or .stp) files. With DesignSpark Mechanical there is a simple trick to unlock the restriction on modifying .step files, you can find it with an internet search. You can use FreeCAD, also free. </div><div><br></div><div>Regards,</div><div>Doug P.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Aug 3, 2018 at 4:54 PM, markus via DPRGlist <span dir="ltr"><<a href="mailto:dprglist@lists.dprg.org" target="_blank">dprglist@lists.dprg.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">FreeCAD can handle those formats.
