Srhenson Posted May 25, 2010 Share Posted May 25, 2010 Hello All, new member here as well as with Inventor. I have searched the interent over and am struggling with this challenge. I have read and learned how to make most of my other parts, but this one is kickin my butt. I am working on a project and I need a cylinder (pipe actually) drawn that is 40" long, 1" OD with a wall thickness of 1/8" and a slot that goes thru both sides (180 degrees apart). The slot is 1/4" wide and needs to be 6 1/4" long. The slot should start 3/4" from the end of the pipe or cylinder. I would appreciate any help or guidance in my problem.

linnmaster Posted May 25, 2010 Share Posted May 25, 2010 Hi. I don't have my Inventor system running currently, but I'll try and word it. It shouldn't be that difficult. If your pipe was created from a sketch on an origin plane constrained centrally to the origin point, then create a sketch on one of the either two origin planes and draw your slot profile which you wish to cut out from the pipe. Your slot should be difined with two dimensions - the 1/4" and the 6 1/4", and the another dimensions defining the position of the slot - which is 3/4" from the end. With these three dimensions, your sketch should be fully constrained. If its not, you need to use other constrains such as tangent, parallel, conincident, etc, etc. Go to extrude, select remove material, select central both ways, and select through all, and it should work. Hope that helps and wasn't too badly worded. Regards, David Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 25, 2010 Author Share Posted May 25, 2010 OK, I'll study on that David. I am alittle slow at Inventor. So far all can really do is to draw a pipe in my dimensions. I will work on trying to get the second plane and then go from there. Thanks Quote Link to comment Share on other sites More sharing options...
linnmaster Posted May 25, 2010 Share Posted May 25, 2010 Study hard and you should be fine Any questions, ask away - others here are very very experinced. I'll attach a file when I get a chance. FYI, you shouldn't need to create a second plane ... Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 25, 2010 Author Share Posted May 25, 2010 Ok, thanks David. I am studing as we speak.... Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 26, 2010 Author Share Posted May 26, 2010 OK, I need a little push. I can draw a circle, dimention it, extrude it to my correct lenght and then shell it to create my pipe. I am assuming that I did the following like David asked me to do......"pipe was created from a sketch on an origin plane constrained centrally to the origin point". How do I "create a sketch on one of the either two origin planes and draw your slot profile which you wish to cut out from the pipe".

JD Mather Posted May 26, 2010 Share Posted May 26, 2010 Your first sketch is out in space. It should be constrained to the origin. http://home.pct.edu/~jmather/AU2006/MA13-3%20Mather.pdf Quote Link to comment Share on other sites More sharing options...

Srhenson Posted May 26, 2010 Author Share Posted May 26, 2010 JD, I cannot open the file you posted. It is a newer version than what I have. Quote Link to comment Share on other sites More sharing options...
linnmaster Posted May 26, 2010 Share Posted May 26, 2010 Attached for your reference in 2009 version. My dimensions are just there to indicate what you should have ... I'm using metric rather than imperial. But that's the simplest way to construct what you're after. Of course, it depends on design intent, but that's a start. Hope that helps. JD'S tutorial is very very very good. I learned a lot from it myself. Best, David main_shaft_DL.zip Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 28, 2010 Author Share Posted May 28, 2010 Thanks David, your example helped alot. I was able to examine your drawing and created my own except for the slot. I am struggling with how to make the slot. I am able to make a hole the goes thru my pipe. I made 2 holes did but cant seem to get how to delete the material from hole to hole. Thanks again, all of the help here has been great. Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 28, 2010 Share Posted May 28, 2010 I made 2 holes did but cant seem to get how to delete the material from hole to hole. Zip and attach what you have completed so far. I will post screen captures to walk you through the process. Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 28, 2010 Author Share Posted May 28, 2010 Here is what I have so far. Along with not knowing how to cut the slot, I also didnt know how to dimension the hole apart or from the end of the pipe. Thanks for your attention and help.

JD Mather Posted May 28, 2010 Share Posted May 28, 2010 Here is what I have so far. I noticed your Sketch1 is not dimensioned and is not constrained to the origin. You might want to go through this document. http://home.pct.edu/~jmather/AU2006/MA13-3%20Mather.pdf Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 28, 2010 Share Posted May 28, 2010 Create a construction line from the projected origin to center the holes. If you are doing a slot you might as well sketch a slot and then Extrude-Cut. Make sure your sketches change color indicating fully constrained.

JD Mather Posted May 28, 2010 Share Posted May 28, 2010 You can also eliminate the Shell feature by simply having two concentric circles in Sketch1. Quote Link to comment Share on other sites More sharing options...
Srhenson Posted May 29, 2010 Author Share Posted May 29, 2010 JD, am I getting closer? I had some struggling with your last couple of post, and the doc you sent was hard for me to understand. Most I felt like it was greek to me.........But I feel like I am progressing. Thanks for you patience. Main_Shaft_rev3.zip Quote Link to comment Share on other sites More sharing options...
JD Mather Posted May 29, 2010 Share Posted May 29, 2010 Sign up for a class. You are missing construction line from image I posted and missing tangent constraints between the lines and the circles. The lines should have vertical constraints. You have two .25 dimensions when only one is needed. Your sketch 2 has not changed color. These topics are normally covered in the first 15 minutes of class. Go back through that paper and Stop and any step you do not understand and ask for clarification here.
