Intersect 2D line with 3D edge

[JQL]

This cannot be performed easily.

In this example I want to trace around this skylight so I can carry the hidden lines to another drawing.

I draw a line around as in here:

Extend SU 3D lines like they were 2D

I need to perform this extesion line but it’s not possible. In sketchup you’d hit the first point, and move the second point on edge, hold shift and start infer the end point. In layout it’s a lot more intricate and envolves holding down shift while scaling the line, so you have to use 2 commands and can’t infer. If the model view would be an actual 2D the issue wouldn’t arise. But the only way to acomplish that is by exploding it wich defeats Layout’s purpose of syncing with SU. [image]

Then I want to find the intersection of that line with the model and I can’t, so I have to create another line in 2D space and then use the knife to break it, and then the eraser to clean excess.

This could be a lot easier to do and it makes tracing objects very hard.

One alternative would be exploding but that is a lot of trouble. Copy pasting lines from sketchup to Layout implies a lot of work too.

Tracing is key for linework and it’s very hard with current model inferencing.
