kuwait Posted April 25, 2010 Share Posted April 25, 2010 helloooooooooooooo:) please check my isometric view and the second picture check the right view i really did my best autocadtutor.dwg autocad2.dwg Quote Link to comment Share on other sites More sharing options...
Cad64 Posted April 25, 2010 Share Posted April 25, 2010 Your dashed lines are incorrect in the side view and the holes are not displayed correctly in the isometric view. Take a good long look at the hole and counterbore in your front view and I think you will see the problem. Quote Link to comment Share on other sites More sharing options...
kuwait Posted April 25, 2010 Author Share Posted April 25, 2010 :)okay now did i miss something? by the way thank you soooooo much autocadtutor.dwg Quote Link to comment Share on other sites More sharing options...
Cad64 Posted April 25, 2010 Share Posted April 25, 2010 That's better, but your dashed lines in the side view are still incorrect. Look at where the hole breaks through the bottom of the part on the front view and then look at your dashed lines in the side view. Quote Link to comment Share on other sites More sharing options...

kuwait Posted April 25, 2010 Author Share Posted April 25, 2010 now see it there is something wrong or not i tried but i couldnt find out where i did wrong autocadtutor.dwg Quote Link to comment Share on other sites More sharing options...
kencaz Posted April 25, 2010 Share Posted April 25, 2010 what do you mean?!! You should be studying 3D. 2D ISO is dead and buried already. KC Quote Link to comment Share on other sites More sharing options...
Cad64 Posted April 25, 2010 Share Posted April 25, 2010 now see itthere is something wrong or not Nope, still not right. There are now two problems where before there was only one problem. Study the front view and look at where the hole breaks through the bottom of the part. Quote Link to comment Share on other sites More sharing options...

KC you are right but this is has nothing to do with my major (mechanical engineers take more than that) i just took this course to learn more (extra) Quote Link to comment Share on other sites More sharing options...
ReMark Posted April 25, 2010 Share Posted April 25, 2010 2D iso is dead and buried? I'm willing to bet there are still a lot of people making them whether we agree with the technique or not. Quote Link to comment Share on other sites More sharing options...
nukecad Posted April 25, 2010 Share Posted April 25, 2010 You should be studying 3D. 2D ISO is dead and buried already. KC Try telling that to the nuclear industry. We draw very long pipe runs on our nuclear site (2 or 3 miles total pipe length). The best way to show them is with a 2D isometric for the long runs and an engineering detail when it gest a bit more complicated. The marketing people like to see 3D for presentations but the guys who have to machine the parts want a 2D drawing with dimensions. Quote Link to comment Share on other sites More sharing options...
ReMark Posted April 25, 2010 Share Posted April 25, 2010 kuwait: The hidden lines in your side view should more or less be the same as you're seeing in the front view with one minor adjustment. As Cad64 tried to point out it is simply a matter of really "looking" at the two views. Quote Link to comment Share on other sites More sharing options...

You can get both ISO and PLAN views from a single 3D model. Sorry for Hijacking your thread Kuwait... KC Quote Link to comment Share on other sites More sharing options...
JD Mather Posted April 25, 2010 Share Posted April 25, 2010 The hole is the same whether in the front view or the side view. I teach my students to simply copy with basepoint from one view to the other. Think of it like this - if you were rotating the real part around the axis of the hole the hidden line view of the hole would not change in any view. It is what it is.

Tankman Posted April 25, 2010 Share Posted April 25, 2010 The marketing people like to see 3D for presentations but the guys who have to machine the parts want a 2D drawing with dimensions. You've got that right! Try supplying an up to date pipe fitting when the spec'd fitting is no longer in production...........anywhere! Drawings were all 2D as requested. I had this problem, Saran™ lined pipe in Vermont. Vermont insisted. Saran™ lined pipe is long out of production, replaced by newer, improved, better than was originally supplied. Darn near an Act of Congress to supply replacement lined steel although the new "stuff" was far superior to Saran™ lined pipe 'n fittings. Service was ambient temp, I proposed PPL (polypropylene) lined steel pipe, ductile iron fittings. Finally, the facility changed the spec. Or, updated their out-of-date specification.

Wilbri Posted April 26, 2010 Share Posted April 26, 2010 You are absolutely right. The marketing person wants to see pretty pictures, whilst the guy on the shop floor actually producing the goods requires information and the simpler the better. So nothing wrong with a comprehensive isometric drawing especially when it comes to piping. I realize that 3D is more advanced and agree with J D Mather that simple mistakes in other views can be overcome by using 3D. Won't comment further regarding 3D, as I am still becoming acquainted with it. Quote Link to comment Share on other sites More sharing options...
Wilbri Posted April 26, 2010 Share Posted April 26, 2010 Having considered my previous submission and realizing that my comment has nothing to do with the subject matter, I do however feel it necessary add some comments before being subjected to a barrage from the 3D advocates. Yes I have seen some very good 3D piping details and look forward to being able to produce them in the future. I believe the best by far to be a demonstration of CADWORX some years ago, in which I was amazed to see how fast a basic process plant layout drawing could be produced in 3D and from which detailed piping ISO's with completed bill of materials could be extracted. The price of the software exceeded my departmental budget so that was that. Quote Link to comment Share on other sites More sharing options...

MikeScott Posted April 27, 2010 Share Posted April 27, 2010 I'm missing something here.. what is it you can do with the isometric drawing that you can't do with 3d? If your guys want iso, give them a view of the 3d. Unless you're referring to making piping symbols? I mean, I used to use the HELL out of isometric before I learned 3d, but aside from quick little one-offs, I don't use it anymore. However, I think it SHOULD be taught, because in creating isometrics, you're also learning to read 3d diagrams. You get the connection between what is supposed to be there, and what isn't. This question we're posting-in is evidence that not everyone can automatically read those. If that were the case, this thread wouldn't exist, because anyone familiar with drawing views would have spotted the two issues at a glance. Of course, I still support teaching elementary math as opposed to allowing calculators in grade school, so maybe I'm just old fashioned.
