Seems like the primary use of ISO views might be for illustration purposes. Where the scale and actual measurements are secondary to clearly communicating the “purpose” of the object in question.
I have been trying to wrap my brain around the concept. The basic definition goes something like," the ability to see 3 sides in one view". Okay, easy enough! But with most CAD software it is straight forward to manipulate a view to accomplish this. Then I noticed in SU, camera>standard views>iso. The angle looks to be 45 degrees. But looking at drafting standards the definition is: where the X and Z axes are inclined to the horizontal plane at the angle of 30⁰.
What am I missing? What is ISO view used for in SU?
Finally, to my real question, can an ISO drawing in 2d be converted into a 3d version, by tracing over the line work and re-scaling appropriately? I am ignoring the issue of raster vs. vector of the original drawing for now (although important!). Or, is there so much work involved (due to inherent distortion), that it is easier to just re-create the object from scratch, using the ISO for reference only. Case in point, I wanted to model the hanger hardware from this ISO drawing (and yes, I know, it’s in the 3D Warehouse, but I need the practice).
