yasir789 Posted December 1, 2012 Share Posted December 1, 2012 (edited) i m a student ...i m learning autocad 2013 in my university our teacher took a quiz and give us a drawing of a pipe bending on 90 degree plz help me wit this Edited December 1, 2012 by yasir789 Quote Link to comment Share on other sites More sharing options...
Organic Posted December 1, 2012 Share Posted December 1, 2012 No one is going to draw it for you. Ask more specific questions if you are having trouble. Quote Link to comment Share on other sites More sharing options...
Cad64 Posted December 1, 2012 Share Posted December 1, 2012 I have renamed your thread to something much more appropriate. "plz help!!!!!!!!!!!!!!!!!!!!!!!" is not an appropriate thread title. And by the way, it's Autocad that you're using, not auto can. Please explain what problems you are having and I'm sure someone will be happy to help you.

Cad64 Posted December 1, 2012 Share Posted December 1, 2012 Bend the pipe? Are you creating a 3D model? Quote Link to comment Share on other sites More sharing options...
yasir789 Posted December 1, 2012 Author Share Posted December 1, 2012 yes i m creating a 3d model Quote Link to comment Share on other sites More sharing options...
Cad64 Posted December 1, 2012 Share Posted December 1, 2012 Ok, this is why it's important to be specific about what you need help with. You should have stated in your first post that you were trying to create a 3D pipe. Until someone else comes along, take a look at this thread: http://www.cadtutor.net/forum/showthread.php?5642-How-do-I-bend-a-3d-cylinder I have moved your thread to the 3D modeling section.

Dadgad Posted December 1, 2012 Share Posted December 1, 2012 (edited) Welcome to the forum. You can use the SWEEP command to sweep the two different sizes of circles (meaning the ID and OD of the pipe) along a path which describes the centerlines of the pipe segments. You do not need to put curves in the path, if you leave the intersections as right angles the software will figure it out when you use the SWEEP command. Create the path using a 3D POLYLINE, and I suggest that you choose an isometric perspective when creating your path, and during the rest of the modeling. After you have swept both of the diameters you will have 2 solids, one representing the ID, which you will have to SUBTRACT from the larger one which represents the outer diameter of the pipe. Follow the commandline prompts carefully. At that point you should be left with an accurate 3D Model of the pipe.

JD Mather Posted December 1, 2012 Share Posted December 1, 2012 I doubt that Sweep will work (self intersecting geometry). If it doesn't - I would create 3 profiles as shown and then do 3 Revolves. Join and then solidedit shell. Quote Link to comment Share on other sites More sharing options...
yasir789 Posted December 1, 2012 Author Share Posted December 1, 2012 sorry bros i cant do it coz i m a beginner .. so ca u pleas send me *.Dwg file plz,plz,plz..... Quote Link to comment Share on other sites More sharing options...
Cad64 Posted December 1, 2012 Share Posted December 1, 2012 sorry bros i cant do it coz i m a beginner .. so ca u pleas send me *.Dwg file plz,plz,plz..... Sorry but we don't do that here. We are a help site. We do not provide finished projects to students. The whole point of this exercise is for you to learn how to build a 3D model of that pipe. If we do it for you, what will you have learned? Quote Link to comment Share on other sites More sharing options...
JD Mather Posted December 1, 2012 Share Posted December 1, 2012 sorry bros i cant do it coz i m a beginner .. ........ What can't you do? Draw a line? Draw a rectangle? Draw and trim a circle? Let's walk through this step-by-step. Make a rectangle 48x7. Attach the dwg file here. Quote Link to comment Share on other sites More sharing options...

ReMark Posted December 2, 2012 Share Posted December 2, 2012 A revolved (90 deg) profile would work. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted December 2, 2012 Share Posted December 2, 2012 Lets start from scratch. Draw a horizontal line 34 long. Draw a vertical line at one end of this horizontal line 7 units long. Attach your file or image of your two lines here. Quote Link to comment Share on other sites More sharing options...
mikekmx Posted December 2, 2012 Share Posted December 2, 2012 sorry bros i cant do it coz i m a beginner .. so ca u pleas send me *.Dwg file plz,plz,plz..... you need to be able to do it yourself, surely? try typing "3d pipe autocad" into yt. it is a fairly basic procedure.

JD Mather Posted December 2, 2012 Share Posted December 2, 2012 My first example was more complicated than needed. Maybe you can figure out from this example Quote Link to comment Share on other sites More sharing options...
mikekmx Posted December 2, 2012 Share Posted December 2, 2012 sorry to butt in, but what is wrong with drawing a pathline and a circle and sweeping the circle along the path? bosh bosh Quote Link to comment Share on other sites More sharing options...
JD Mather Posted December 2, 2012 Share Posted December 2, 2012 sorry to butt in, but what is wrong with drawing a pathline and a circle and sweeping the circle along the path? bosh bosh Attach your proposed solution here (or picture of...). What's wrong with your solution? I don't know because I didn't try it, because I don't believe it will work. Quote Link to comment Share on other sites More sharing options...
