Remove Asset data from CAD entities.

Sometimes we need to strip the ADAC asset data off the geometry in our drawing. For example, we may have tagged a long polyline as a pipe. Later we realise that different segments of this pipe have different diameters, so they must be recorded as separate assets.

In our drawing, all assets are stored as BLOCKS. If we simply select the BLOCK in BricsCAD and type EXPLODE or EXP, we are left with the original 'dumb' geometry. We could then EXPLODE the polyline into separate lines, then JOIN some of these lines again to create the entities we need.
