Hi, Working with straight shapes in Solidworks is a blast but as soon as you start getting creative with curves things can get ugly ( shells not working, surfaces don't match up, faces don't want to offset.. Ai yai yai )... I made a plastic enclosure to be molded, although I could not finish a shell on the base part, so I had to rely on the plastic injection company designer (Chinese) which seems to be too busy to follow instructions properly; and he's using a different program (Pro/E UG). Point is, I can't rely on him and I'd like to do it myself in the future. This is where i need your help. In order to make the thing myself, I need some serious help. I need to fix the base part design, and round out the four sharp edges (see image) so that I can pull off that shell. I don't want any sharp edges. Unfortunately, I couldn't figure out how to make surface flow consistently. There must be something wrong with my methods. The corner of the display/surface part also got chewed up by the shell.. no idea.. I TRIED to attach the 3D part but the limit is too small (i need 15MB and dropbox is blocked in China.. HATE), I rolled back to a previous state before the bosses, ribs, snap hooks, port holes, etc.). Who knows? Maybe it's easy for you. If you want to give it a shot, just email me at matt_thetulip at hotmail.com and I'll send it to you and you can send it to me back if you figure it out. I'll unveil the methods in which you used in this post thereafter, so everyone can benefit. Thanks
I am looking for the detailed dimensions of standard threads used on plastic parts. I need both the internal and external thread details. Specifically I am looking for threads in the range of 50mm to 100mm. I can also work with specifications in inches. I am willing to buy the appropriate reference books or standards that provide this information, but I do not know the name of these resources. I have already purchased a few books that did not include the required information. I have previously found this information in plastic reference books in the possession of a local mold maker, but I no longer have access to his library. Any suggestions would be appreciated.
