Currently, sizes for line are used for lines, that represent some sort of area. In fact - it is now allowed just for line slope. This would be different interpretation of size.

OK, I suspected as much. However r-size throws an error with line slope, so perhaps there is another linetype for which it works as well?

Could you please add a picture, to understand this problem? Is it not possible to solve it using scale/base-scale combination?

I was wanting a case by case scaling of the line subtype scaling (ie the tick marks, sand shading or pit triangles) within a drawing that has standard sized symbols for most of the lines. Scale/base-scale would affect the whole drawing.

I am afraid, in any case modification of metapost symbol is needed. May be, some sort of -scale option, as it is used for point would help also.

Yes, this is what I was thinking. It is not that important to me. As much as anything I was just making sure that therion did not have some feature that I was not making good use of!

It seems it is not allowed, but I was hoping to be able to invoke a reduced symbol size for a small narrow pit entrance. Perhaps I have misinterpreted the authors intention for this option? .therion.exe: error -- aePit-BiclopsPlan.th2 [14] -- r-size not valid with type wall Thanks Bruce _______________________________________________ Therion mailing list Therion@speleo.sk http://mailman.speleo.sk/mailman/listinfo/therion
