The resulting programs end up being too large for their old machines.<br /><br />I wrote a program that took in a DXF file, finds all the closed contours, then finds all the sections of the closed contours that can be replaced by circular arcs. Then it does so, and spits out a new simplified DXF. It mostly works and saves them time. Sounds like maybe not the same problem, but a similar one?<br /><br />MadRocketSci<br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-16176200027704695832021-07-05T14:11:54.718-04:002021-07-05T14:11:54.718-04:00I appreciate the offer, but I should suck it up an...I appreciate the offer, but I should suck it up and do it. I have built countless parts from 2D drawings over the years. These parts are just a bit more complex than that. <br /><br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-24037757516019424452021-07-05T13:21:24.749-04:002021-07-05T13:21:24.749-04:00How many parts do you need converted?

I may be able to draw them into autocad format (which I could then export to dxf) for you.My Takehttps://www.blogger.com/profile/09391078011896611814noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-66141378553604398772021-07-05T11:27:35.962-04:002021-07-05T11:27:35.962-04:00SiG, for a lot of parts, it really is a lot simple...SiG, for a lot of parts, it really is a lot simpler just to use the PDF as a reference and build the model from scratch. That example you gave would have taken me about 25 minutes to model in Inventor. I admit I don't know how easy it is to model in Rhino.Malatropehttps://www.blogger.com/profile/06130944283006020214noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-23113618238065811982021-07-05T07:30:21.666-04:002021-07-05T07:30:21.666-04:00Sorry I wasn't clear: the point isn't to r...Sorry I wasn't clear: the point isn't to <i>read</i> the files. I have Acrobat Reader on everything here. I read the files all the time. <br /><br />The point was to turn them into CAD drawings, which is always a tedious process. I need to create solid models which is another step beyond that. <br /><br />As it is, I keep the drawing open in Acrobat reader and go back and forth between it and Rhino constantly as I try to make the solid models. <br />SiGraybeardhttps://www.blogger.com/profile/00280583031339062059noreply@blogger.comtag:blogger.com,1999:blog-1592992209402300549.post-35547312006105622622021-07-05T02:45:44.213-04:002021-07-05T02:45:44.213-04:00Try reading the PDF file using Adobe Acrobat inste...Try reading the PDF file using Adobe Acrobat instead of Rhino. Solidworks drawings, like those in Pro/e, are created parametrically from the solid model. You can view the drawing using the Solidworks Software but to print them out you have to create PDF copies which are not parametric. They’re just dumb copies of the drawing created in Solidworks. It appears Rhino is attempting to interpret the PDF text and is providing a very bad interpretation. CPhttps://www.blogger.com/profile/08280724039889332724noreply@blogger.com
