pqphillips Posted January 16, 2013 Posted January 16, 2013 Hey folks, I have a question... I have a tube modeled in AutoCAD that is 1.5" OD and 1.25" ID. Along with it, I have a piece of flat 2D geometry representing a pattern to be cut into it. Is there a way to either wrap the geometry around the tube and extrude out the shapes, or a way to extrude the geometry to the correct thickness and wrap it into a 1.5" OD tube? Thank you so much in advance. Quote
JD Mather Posted January 16, 2013 Posted January 16, 2013 Autodesk Inventor will do this. Can you attach the dwg file here? Quote
pqphillips Posted January 16, 2013 Author Posted January 16, 2013 Autodesk Inventor will do this.Can you attach the dwg file here? Which do you want? The tube and geometry, or the extruded geometry? EDIT: I was mistaken. The ID of the tube is 1.5" and the OD is 1.65" Quote
JD Mather Posted January 17, 2013 Posted January 17, 2013 Just give me everything and end all doubt. Quote
ReMark Posted January 17, 2013 Posted January 17, 2013 The topic has been covered in a previous thread. I'm assuming you are using plain AutoCAD and not Inventor. Is that correct? Quote

ReMark Posted January 18, 2013 Posted January 18, 2013 scj: It looks like part of the pattern missing. Did you use a program other than AutoCAD? Why is your cylinder a mesh? pqp: When you say you want the pattern "cut into" the cylinder you want material removed from the wall of the cylinder (depth = ??) or do you want the pattern "imprinted" on the surface of the cylinder?

ReMark Posted January 18, 2013 Posted January 18, 2013 Just fooling around. I cut the pattern into the face of the cylinder a depth of 0.02 then colored the faces. Quote
ReMark Posted January 18, 2013 Posted January 18, 2013 The remainder of the pattern. What is the proper terminology for cutting a shape into an object? Is it "incised"? Now all I have to do is put it all together. I should have done it on the full cylinder but originally I never expected to go this far with it. My bad. Quote
JD Mather Posted January 18, 2013 Posted January 18, 2013 I never expected to go this far with it. Are you doing a true wrap of the geometry onto the cylinder or are you simply projecting? Quote
ReMark Posted January 18, 2013 Posted January 18, 2013 JDM: Really? You're asking me that question? I did not become suddenly rich enough over night to afford buying Inventor. Still using that old dinosaur AutoCAD JD. I projected, used the Intefere command and took it from there. When AutoDesk sees fit to add a wrapping feature to AutoCAD (maybe they did to 2013 and I just haven't stumbled across it) then I'll change my archaic ways. That's why I asked scj what he used. Note that the OP is using Electrical 2013 too. No mention of Inventor. Quote

But seriously, I meant removed entirely. The purpose of this is to allow someone to print the pattern, cut it out, glue it to a piece of aluminum tubing, and cut away with a Dremel. Quote
ReMark Posted January 18, 2013 Posted January 18, 2013 I guess that clears things up. Well as you can see from JDM's comment the geometry that you have would have to be wrapped around the cylinder which is something that I can't do using AutoCAD for one of two reasons. First. The command does not exist. Second. The command does exist and I am just not aware of it, hence I do not have the ability to demonstrate to you how the task would be accomplished. I know that it can be done in Inventor and if JDM has a mind to maybe he would assist you with the task. Or maybe there is another program (Inventor Fusion?) that can be used. I just don't know. BTW...using AutoCAD I could just punch the geometry right through the cylinder and do a subtraction. It would kind of look right but in reality it definitely would not be. Know what I am saying?

scj Posted January 18, 2013 Posted January 18, 2013 Hi, normaly I do the imprinting onto REVSURFs or RULESURFs in AutoCAD, but her I used the BRICSCAD-version (I have no version of AutoCAD available to read the 2010-format yet). The program is written in AutoLISP, using cylindrical coordinate systems. Regards Jochen PS. See the FF.dwg too - it is a little bit late... 1_8_1.dwg FF.dwg Quote
ReMark Posted January 18, 2013 Posted January 18, 2013 That explains the message about not being created with an AutoDesk product. So you have a lisp program that will wrap a 2D design around a 3D cylinder? Where did you find that little gem or did you write it yourself? Quote
scj Posted January 18, 2013 Posted January 18, 2013 Hi Remark, I did it. See some similar things at http://www.ant-ares.de (hope I will not be banned...) Regards Jochen Quote
JD Mather Posted January 18, 2013 Posted January 18, 2013 Something like this? Well, I tried to attach the dwg file but it was too large. see images Wrapped Engraving.zip Quote
ReMark Posted January 18, 2013 Posted January 18, 2013 Banned? Why? Is it a warez site? Something a little on the shady side? I'm not visiting a link they may introduce problems I don't currently have (ex. - malware or a virus). Can't be too careful these days. Quote
