Adding a vertex onto an angled edge in precise X position I'm designing a part for 3D printing, but I do not know how to cut an angled edge at a precise absolute X position. I marked in red the place where I would like to insert a vertex. It's exactly 2 units (millimeters) from the left. So far I was unable to achieve this with desired precision.



EDIT

First attempt. Using GG to move the vertex along the line and snapping to another vertex failed because apparently this tool uses local reference system.



Second attempt. using TinyCAD plugin. Worked perfectly!
I created a second edge that intersected the angled one, and used XALL to insert a vertex on the intersection.
You could subdivide the edge to add a vertex. Select the vertex and press GG to slide the vert. Make sure snapping is set to vertex and then click on the vert shown at 2 units above. This should line up the lower vertex on the angled line with the vertex above

The vertex above could be place at 2 units with snapping set to increment absolute grid.

 Answer above incorrect. New solution:

Ok this one bugged me as it should be possible to do this. I turned on edge length in the overlay



I subdivided the angled edge to create a vert and then GG and dragged the vert to the starting vert on the edge. I am working in m so in the image you can see 0m.



With the vert still selected I dragged it back along the angled edge whilst holding shift to get a more precise value. I moved the vert until it was at 0.5m



Should be able to use this technique for other stuff
