Setting up a dimetric grid with plane sets

Recommended Posts

up_spacing =  sin(first_angle) * first_spacing * 2

This formula does seem to solve the alignment of 2 of the 3 planes, but the downside is that the grid isn't uniform anymore, making it impossible to make proportional cubes for example.

I don't know if this is possible but it seems to me that the solution is to shift the plane consisting of the first and up axis and the plane consisting of the second and up axis down or up to align with the plane consisting of the first and second axis.

I would really like to have other grid types be able to have aligned plane sets, just as the isometric grid type does.

Yes it's pretty frustrating, you can't get a single point to align with all the different plane sets unless in the standard 1:1 isometric mode. I still didn't figure out a way to do it.

Try beta 1.7. There is the option to move the grid origin.

Still seeing the same sort of issues, in the gif below I went to "Grid and Snapping Axis", chose "Dimetric", when drawing a shape it only intersects with the grid lines on max. 2 out of 3 planes.

For your type of drawing have you ever taken a look at Hexels?

I've heard of it but never used it. I mainly do design for web applications in Sketch but when I do the occasional landing page design I like being able to do simple isometric-style illustrations and then bring them across into Sketch. Couple of examples attached, would Hexels be a good tool for that sort of thing? I find that when I do standard 1:1 isometric illustration then affinity is great but any other sort of axonometric projection is quite tricky, also slightly missing some sort of tool for setting the lighting/shading would be handy.

Like I said, It is because you need to move the grid origin.  Enable “show axis editing handles”, then you can move the grid origin.  The origin will remain fixed as you change between planes.  To draw a cube, you would place the origin point at the prominent corner of the cube (the corner closest to you, where all three plane intersect).  For anything other than isometric, you will need to reposition the origin to work at different distances through each plane.  This is to be expected for any grid that is not isometric, as the axis proportions are not equal.

 

this is also only an issue if you also intend to work on grid.  You could just use the planes to define the axis of constraint and snapping.
