Exerice : ex-isometric.slvs (by Ektor)
Hello.

I tried to reproduce this exercise available on the site.
But I can't do it. If you have any advice, I am listening.
I try things, but it doesn't work. I think I'm missing some information, some tip.


Thank you

Maybe it would be good to say what example you tried.

It is just a demonstration of how the isometric view works. Don't look for science in that.

Make a 3d model. Rotate to roughly isometric. Click the isometric view on the toolbar. What else are you trying to do?

I was talking about this file in attachment.

available on the solvespace site in the "examples" section.
in the part "Geometric construction of an isometric view".

I want to reproduce it, but I can't...

In the first group, Sketch -> Anywhere In 3d and then sketch the three lines, and constrain them equal-length and parallel to each coordinate axis. Then in the second group, Sketch -> Workplane to create an unconstrained workplane; you can drag it around to translate, and shift-drag to rotate. Select that workplane and Sketch -> In Workplane, then constrain the lines to be equal length. Also constrain one of the lines vertical.

That causes the solver to adjust the workplane orientation until the three coordinate axes have equal length projected into that plane. This is the definition of an isometric view. The additional vertical constraint determines which axis is facing up.

Note that this is backwards from how workplanes are typically used. Typically we know the workplane geometry, and then we use that to solve for the position of lines in that workplane. We can work in the other direction too though, solving for the position and orientation of the workplane in terms of already-fixed lines.

Of course this is just a demo. If you want an isometric view for practical purposes, then View -> Nearest Isometric View as Paul says.
