Yes John the "drawing" is 2D but I hope that the informatic work was done in 3D and not with the "like on the drawing board old way".

I have never really done 2D isometric drawing or only for scheme or pipings with symbols but now with the "real" 3D we can do all this better and quicker.

The level of detail shown on the drawings makes me think that it's real 3D.

Eventually see my AutoCAD file :

in the CAD/BIM Blocks library done in answer of a cad discussion.

I had realized a 2D isometric drawing from an image file by doing real 3D solids and then FLATSHOT it.

I never though the drawing was 3D. Always looked 2D to me.]]>

Dery, if you do a search on the internet you will find the various projections : isometric, dimetric with their diffrerent settings on the angles and length ( dimetric = 2 angles and length are equal, isometric = 3 angles and length are equal ).

The drawings are not isometric and not dimetric but from a 3D point of view ( isometric modified to see better the elements ).

Is your work 2D or 3D, I hope it's 3D because is now less work than the old way to draw.

What do you mean by "2D isometric view using dimetric projection"? I don't understand. Do you mean the projection is combined? Clearly it can be seen that the drawing is not isometric projection.

That's why ask the question because it does not look like an isometric projection to me.

In fact The angle "A" is greater than the angle "C" and you can check it for example by redrawing an object with a paper on your screen and measuring the angles or rotating that paper for a check on the other angle.]]>

on a 3D object, how can we set the DDVIEWPOINT angles to have a good dimetric view ?

I believe it could very well be a 2D isometric view using dimetric projection.]]>
