Damon :) Posted September 17, 2014 Share Posted September 17, 2014 Why produce isometric drawings in the 2D environment? Quote Link to comment Share on other sites More sharing options...
Dadgad Posted September 17, 2014 Share Posted September 17, 2014 Because they offer enhanced visualization of 3D objects. There are quite a few different ways they can be generated automagically by the software, Viewbase, Solprof, Soldraw, Flatshot, or Flatten, just to name a few.

nestly Posted September 17, 2014 Share Posted September 17, 2014 I read the question not about a need for isometric drawings, but whether to create them from scratch in 2D, or whether to create them by building a 3D model then creating 2D projections. I haven't done the former for many years, but I suppose it depends on several factors, not the least of which is whether the draftsman and/or software is capable of 3D modeling (ie LT vs Full) Quote Link to comment Share on other sites More sharing options...
nukecad Posted September 17, 2014 Share Posted September 17, 2014 It goes back to when we didnt have CAD and used pen and paper. There was no 3D. The best way to visualise pipe runs etc. in those days was to draw them in isometric. And as nestly says not all software can do 3D even now.

Damon :) Posted September 17, 2014 Author Share Posted September 17, 2014 That's great thank you. So why is it useful to still draw isometrics in the 2D environment? Quote Link to comment Share on other sites More sharing options...
rkent Posted September 17, 2014 Share Posted September 17, 2014 That's great thank you. So why is it useful to still draw isometrics in the 2D environment? There may be an occasion where a very small iso is easier than doing a 3D model but for most anything the model is a better idea. Easier to use existing blocks, text, dims, etc. on a 3D model. If something changes you only change it in one place. The only real reason I can think of to use 2D Iso Projection is if you like it enough to use it, you know, nostalgia.

ReMark Posted September 17, 2014 Share Posted September 17, 2014 It isn't unless what you are using (pen & paper or some 2D CAD program) is not up to the task. Quote Link to comment Share on other sites More sharing options...
nukecad Posted September 17, 2014 Share Posted September 17, 2014 If the customer asks for, and pays for, 2D isometrics thats what we draw and send to him. Quote Link to comment Share on other sites More sharing options...
