Changing class pen style and weight

[Greg Thompson]

I have a script in floor plan for a wall framing plan view that changes a class' pen style to dashed, the weight to lighter, and the color to blue.

SetClLS('Walls',-1);

SetClLW('Walls',7);

SetClPenFore('Walls',4)

When I go back to the floor plan view, the class' pen style goes back to solid, the weight goes back to heavier, and the color returns to black.

SetClLS('Walls',0);

SetClLW('Walls',20);

SetClPenFore('Walls',255)

However, the class setting for pen style permanently changes to 'None', and if I re-set this to 'Solid', the pen weight changes to .10.
