It is possible to pull down an angle guideline and change the degrees to whatever is needed, 25 degrees for example. Your object can snap to this guide and move across it. Would that help you in any way?

I do have some questions concerning technical linedrawings with inkscape:

1. I take a screenshot of 3D-CAD a model that is rotated in a standard

axonometric view. For example an isometric projection 30°-30°. 2. I import the screenshot into inkscape. 3. In "inkscape preferences" dialog in option "steps" Is set "rotation snaps every" to 30°. 4. By holding down "Strg" I can easily trace the screenshot.

However when I have the 3D-CAD model rotated to some other axonometric view, for example 25-25°. This helpful technique is no more possible, since I can only choose from a list of predifined values in "rotation snaps every". I´d like to put in any kind of value. Should this be on the wishlist?

Another question: I want to move an object along a defined axis. When I hold down "strg" I can move a selected object along the vertical and horizontal axis. Are there ways and techniques in inkscape to do that kind of thing along any kind of axis.

Thanks for your help Marcel

I think the 'rotation snaps every' setting cannot accept arbitrary values. They have to be integer divisions of 360 degrees: 360 / 2 = 180 deg 360 / 3 = 120 deg 360 / 4 = 90 deg 360 / 5 = 72 deg 360 / 6 = 60 deg etc. 25 degrees is not possible, because if you go in steps of 25 around a circle, after one round you won't end up where you started: 0 25 50 ... 350 375 = 15 40 65 ... Inkscape would snap to lots of angles this way.

Have you seen Inkscape's axonometric grid? Maybe that can help you out a bit.
