Concrete floor deck

[Anonymous]

In using the Roof Accessory tool to generate a concrete floor slab that has a unique shape.....has anyone been able to SEO the deck from the concrete 'roof' so that in section it appears properly? Right now the SEO doesn't want to work (particulary for the holes that I have in the concrete slab)

The corrugated deck tool within the steel library doesn't allow for unique shapes (it's only rectangular )

logically working through the macro it seems that the FOR/NEXT loops simply need running in reverse after a dropping down by the thickness of the sheet?

ah. i see that this is the first big problem . . . having no idea where the polyline has got to in order to determine the drop down node.

on a plus, i see in the manual that the EXTRUDE command doesn't actually need a closed polygon in order to work. that's a relief, eh?!

Hello Ben,
You are right. You have to run the buffer values in reverse
with a subtraction value in the Y parameters.
This involves writing another set of put statements.

You can tell where the polyline has got to easily enough.
It is the last calculated set of X and Y parameters in the buffer.

Hello,
Just for fun, I edited a copy of the macro
"Trapezoid Sheet.gsm" so that it was a solid
and named it "Trapezoid Sheet Solid.gsm".
I made the surfacer object call this new
macro rather than Trapezoid Sheet.
I can get this object to subtract with
upwards extrusion but if I try to
subtract with downward extrusion
it just subtracts. No downward extrusion.
The object is solid and it has a thickness of
3/64", a little over a millimeter
and it is participating in the SEO
so I don't think this is a problem
with the object.
Anyone run into this ?

Maybe this inability to subtract with downward extrusion
has something to do with the fact that the object is a macro
called by the roof surfacer accessory.
I saved the macro "Trapezoid Sheet Solid.gsm"
as an ordinary placable model element under
a different name and placed it at the underside
of a roof and it did the subtract with downward
extrusion with no problem.
To bad I can't get this to work
so that the shape of the roof and all holes
in the roof are drawn by the accessory.
As it is, the object can be placed, stretched
to the dimensions of the roof,
the SEO performed, and the object
put on a hidden layer.
