One can use Inkscape's dialog Object > Transform. To convert the reconstructed flat faces to your original isometric projection is simple. If the rotation axis was arbitary I wouldn't try to do the same in Inkscape, it would be much easier to use a 3D program (see NOTE1) - no matter the construction has been known hundreds of years as a part of engineering. The method is usable as well with other rotation angles, but the rotation axis must be parallel with one of the edges of the original box. The angle is still undefined, but I guess it can be 30 degrees. The rotation is wanted around an axis which is parallel with the z axis. We construct from these a copy of your original isometric box and a rotated version of it. There's no need to draw the 3rd (=top) face, it comes automatically right because this is a rectangular box. The red one is 19 millimeters wide and the other is 16 millimeters wide. I counted the grid divisions of your "TEST" box, assumed that 1 div = 1 millimeter and drew 2 flat straight on the face rectangles of the same box.īoth are 26 millimeters tall. Without that knowledge you do better by drawing a new box. It's possible if one knows and understands 3D projection math and how it can be used in Inkscape. There's no easy way to transform the already drawn box to the new rotation. You can see here how users can create the appearance of 3D in Inkscape, but they aren't creating actual 3D objects: Inkscape has no clue what Z is or that it even exists. Inkscape, like all 2D applications, understands X and Y on flat, perpendicular planes. If you wish to change the view angle, you must redraw at the angle you want. As far as I'm aware, Inkscape doesn't create real 3D projections, including isometric projections. It's still just flat 2D objects which have had angles adjusted to appear dimensional.Īny apparent dimensioning is just appearance, not real dimensional projections. The above may look like a 3D projection at the end, but it's not. This animation doesn't utilize Inkscape specifically, but to explain further. Similar to what can be created in any 2D vector application. You can pull the rectangles apart and see that there's absolutely no 3D projections taking place. just 3 rectangles with sides at various angles, that's all. What you have are flat, non-dimensional, objects. What you want to do is not possible in Inkscape, unfortunately. You are seeking 3D functionality in a non-3D application. However, Inkscape is not a 3D application.
