Snap precision issue

[JKayten]

I did another set of screen shots regarding the boolean awkwardness.

In this model I’m needing to reduce the floor size of an octagonal space. What I want to happen is to drag a wall along it’s ortho axis and trim or boolean difference the associated wall.

Starting with the plan curves both walls are extruded.

Next in the top view with the boolean operation and resulting object

Next, the need to trim away the unwanted remaining on the left by duplicating an edge of the cutting object. ANd the next result.

This is what makes me wonder if my profiles created using the snaps function are accurate.

I understand as per David the result is out of my control as the algorithm isn’t written to do this particular sort of task, It would be grand if it did I think.

The other issue is with the creation of cabinetry with the plan curves resulting further down the process with minor overlapping of objects that should be adjacent - which being in a 45 degree relationship makes for a lot of recreation to make the necessary adjustments.
