Hello,
I have been wondering for some time how to draw a given radius circle tangent to two crossing lines.
Here is the solution I found and I would welcome any other suggestions.
1- draw two crossing lines.
2- create a construction layer.
3- Build the same two lines on the new layer, they will be endless.
4- Still on the construction layer, draw a fillet with the required radius,
5- On the drawing layer, draw a circle with the "centre, point" tool, using the centre of the fillet and its radius.
The lines and circle will be perfectly tangent, for instance the "trim" will work on both lines.

Regards,

Christian
