ReMark Posted January 9, 2017 Posted January 9, 2017 I would have to take a closer look at your drawing to be able to answer that question. Where exactly are you located? I ask mainly to see what the time difference may be between our two locations. BTW...I have to be away from my desk for a couple of hours but I will check back later. Quote
Robert Newton Posted January 9, 2017 Posted January 9, 2017 I am in the Spartanburg/Greenville area of SC --- same time zone luckily. Quote
ReMark Posted January 9, 2017 Posted January 9, 2017 (edited) Too bad you weren't closer to North Charleston. I may be visiting SC in April. I'd swing by and have a beer with you. So back to your drawing. Looks like you have two objects that are solids...the handle and the two o-rings. Everything else is either a surface or a revolved surface. Typically if you extrude, or revolve, a line or series of lines you'll end up with a surface. If however you extrude, or revolve, a closed (polyline) profile you'll end up with a solid.

ReMark Posted January 9, 2017 Posted January 9, 2017 Two examples both showing a revolved series of lines (on the left) versus a revolved profile consisting of a single continuous polyline (on the right). Result = revolvedsurface (on the left) and a solid (on the right). The pale green line you see represents the point I used for revolving the entities. Example 1 (visual style: 2Dwireframe) > Example 2 (visual style: Conceptual) > And here is an example of what the solid would look like if we sliced it in half. Visual style: Conceptual. Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 So u are suggesting starting over? Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 By the way, I like the N. Charleston idea thingy. Maybe fate will step in and something happen. Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 (edited) So u are suggesting starting over? Not necessarily. If you have retained the individual lines that you used to create the surfaces they can be turned into polylines then joined to create a half profile that can then be revolved thus yielding a solid. Other methods of converting surfaces to solids include... -THICKEN -SURFSCULPT -CONVTOSOLID I've changed my mind. Start over. I can't quite seem to figure out what you did with the cylindrical objects. Perhaps when I get a moment I'll approach the problem differently. Edited January 10, 2017 by ReMark Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 OK...let's talk about the vacuum cylinder. I recreated it as a 3D solid model. What I want to know is, where you see the two red circles, is there supposed to be a space between the inner and outer walls? It appears that in your surface model there was. I don't know if that was intentional or not. Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 Indeed, I tried to simulate a 1/8" space between the two walls thus creating a vacuum. I must have got that part right, else u would not have picked up on it. Ok, I will start over. Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 So what is the thickness of each wall supposed to be? Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 I am attempting .014 wall thickness. Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 OK. I think I got it. I created the profile, on the left (in white), turned it into a region using the REGION command then revolved it (180 degrees in this case). The walls are .014 thick and the space between them is .125 as per your posts. Visual style = X-ray Here is a close up of the upper portion of the cylinder. Visual style = Realistic. I used the COLORFACES command to change the color of the interior face of the outer wall. Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 Wow! I have really got my work cut out now; wonder why the closing radius is not showing up on the bottom? Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 (edited) I'm not sure I follow. Closing radius on bottom? Are you saying the bottom pretty much looks like the top (i.e. - rounded)? Next up. What should I know about the object on the bottom housing layer (color = blue)? It appears you used splines to create the object. Is that correct? Also, take a real good, close-up look at the top edge and tell me if you see anything unusual about the way it looks. Edited January 10, 2017 by ReMark Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 Yes, the bottom will look like the top. I think I used splines toward the bottom of the bottom housing. I will look at the top, as you suggest, but in the mean time do u think it advantageous for me to send u my 2D drawing so u will better understand what we are trying to accomplish? Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 Re: Vacuum cylinder. The bottom is curved like the top. OK. Guess I need to make a change to the profile. Re: Bottom housing. Your short splines (that almost look like arcs) do not transition smoothly into the longer splines that form the outer sloped edge. If you'd like to share your 2D drawing that's fine with me. You can just attach it to a subsequent post. Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 Would it appropriate that we talk on the phone before I put the file on this forum? Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 Would it appropriate that we talk on the phone before I put the file on this forum? Why not just PM me since you have enough posts now to do so. Quote
ReMark Posted January 10, 2017 Posted January 10, 2017 I had to rework the profile of the bottom housing (shown in white on the left) to make this work. I substituted arcs for the splines. It is a 3D solid. Quote
Robert Newton Posted January 10, 2017 Posted January 10, 2017 Got me on the 'PM' --- what do dat mean? Quote
