Trace a Vector

Question

Hi Everyone, I am trying to trace a building plan from a vector image (which I have converted from raster, assume this was the right step) attached. I have set up a polygon feature class and am trying to use the trace tool, but it is so slow as to be unusable. Is this the speed of my laptop? Am I right to use a polygon feature class for this building plan anyway? I later want to create a 3D of this plan.... Many thanks

Laptop:

Processor: Intel(R) Core(TM) i7-10510U CPU @ 1.80GHz (8 CPUs), ~2.3GHz
Memory: 16384MB RAM

If that is a polygon, there appears to either be some custom/weird fill pattern on it, OR, it is a bunch of tiny polygons inside the boundary.

I suspect it is a bunch of tiny polygons and the trace tool is getting overwhelmed trying to figure out which of the many edges to "follow".  If so, depending on the accuracy needed, you could dissolve the polygon(s) into a single polygon that the trace tool should be able to easily follow.  Or, you could just use the create polygon tool and click the 4 corners, rather than the trace tool.
