Can someone please tell me what kind of projection (for example: isometric, dimetric, etc.) is this? (Please see below image for more detail)
Thank you |

Hello dery, I think it's a 3D point of view based on an isometric view modified so that to see better the different elements.
If you do some 3D work, take a "standard" isometric point of view then modify it to see better the object(s). Launch the command DDVPOINT and see the angle : relative to UCS If the object is tall then lower the "vertical" ( relative to UCS ) angle to see "inside" your object, 35.3° modified to 25° for example. If the object is flat then increase the "vertical" ( relative to UCS ) angle to see "on top" of your object, 35.3° modified to 45° for example. Edited by philippe JOSEPH - 18.Oct.2019 at 13:01 |

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

OK John and dery but I don't see equal the 2 angles "A" and "C".
If it's a 3D point of view on a 3D object, how can we set the DDVIEWPOINT angles to have a good dimetric view ? |

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.

Valid for everybody : See the related CAD tip N° 4793:Dimetry - dimetric projection of AutoCAD 3D objects.

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

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.

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.

And the answer is : ........................................................................ TRIMETRIC...........................................................
