sean214 Posted November 13, 2012 Author Share Posted November 13, 2012 are they correct? Quote Link to comment Share on other sites More sharing options...
iainlines Posted November 13, 2012 Share Posted November 13, 2012 On the right hand view there are two holes that don't appear on the isometric viewAssuming this is third angle projection Quote Link to comment Share on other sites More sharing options...
JD Mather Posted November 13, 2012 Share Posted November 13, 2012 You posted orthographic views, not isometric view. Isometric is the image on graph divisions that you started with. Your views are almost all wrong, particularly the right side view has extra circles that who knows where those came from and the top view is a different depth front to back than in the right side view. You have object lines where you should have center lines. Quote Link to comment Share on other sites More sharing options...
sean214 Posted November 13, 2012 Author Share Posted November 13, 2012 Is this right view corect Quote Link to comment Share on other sites More sharing options...
iainlines Posted November 13, 2012 Share Posted November 13, 2012 The hidden detail lines for the large hole are missing but otherwise it looks right. I am only looking at the snapshot, not the drawing file Quote Link to comment Share on other sites More sharing options...

ReMark Posted November 13, 2012 Share Posted November 13, 2012 AutoCAD 2012 I see. Good. Construct the object in 3D then use the Base View command (Annotate tab > Drawing Views panel) to create the three views. Just a quick mock up. No real dimensions used in the creation. Reproduce at your own risk. Quote Link to comment Share on other sites More sharing options...

Reproduce at your own risk. Normally I would agree with you on using Base View (or is it Viewbase?) in a production environtment. In this case I'm guessing it is an exercise and the more important lesson is learning the basics of orthographic projection. Maybe the use of viewbase for self checking after creating the views?

Maybe the use of viewbase for self checking after creating the views? I am still required to teach old-school orthgraphic projection like the assignment in this thread. Funny thing is though - I always solve as 2d generated from 3d to generate my key before I ever walking into the classroom to demonstrate the old-school technique.

That's perfectly understandable J.D. you know what you're doing and need to get things done in a timely fashion. Your students on the other hand must learn what an orthographic view is and how to produce one. Remember the old board method of projecting lines from a 45 degree line?

danellis Posted November 15, 2012 Share Posted November 15, 2012 Remember the old board method of projecting lines from a 45 degree line? Yes. I still use that method in AutoCAD when I'm working in 2D - I even use a variant where I use a line at another angle if I have a cranked/angled unit. dJE Quote Link to comment Share on other sites More sharing options...

I still use that method in AutoCAD when I'm working in 2D - I even use a variant where I use a line at another angle if I have a cranked/angled unit. dJE I've done that as well. Years ago I took a class called 3D descriptive geometry that introduce me to methods for using projection planes and lines for finding intersections and such. It was somewhat involved and I'm a little fuzzy on the methods now. Quote Link to comment Share on other sites More sharing options...
