REQUEST line type definition

Bruce — Thu, 03 Aug 2017 08:29:38 GMT

Is there a way to query a line type definition?

I would like to mimic the user-selected line type in 3D, but can't without knowing the dash and gap definitions of the line type in question.

I've looked through the REQUEST section of the GDL guide, but can't see anything.

I don't see any such REQUEST command either.

I guess this would be rather complicated because there are not only simple linetypes what are composed of Dashes and Gap, but also Symbol linetypes, that could be composed of any number of line segments and arc, their position, size, rotation, etc. Sounds kind of hard to query such a linetype definition.

I agree - to a point. But this definition is stored in the active file, so should (technically) be able to be queried.

However, I am only after a simplified return - it would have to be assumed that the GDL script would only be useful in dealing with non-symbol line types.

If the REQUEST returned an array of dash and gap lengths, this would suffice. Seeing as symbol fills also have these dash and gap fields, it would still retrieve the values, so could still be interpreted (i.e. not fail if the user chose a symbol line type).

An example code snippet would be:

DIM ltDef[][]

rrr = REQUEST("Line_type_definition", gs_line_type, ltDef)

The result would then be something like:
1, 0.004, 0.001
2, 0.002, 0.002

Oh well, maybe it will happen after beam cover fills

Make a wish for it so we can vote. Then I can submit the wish to GRAPHISOFT. Please post the link of the wish into this thread.
