Hi,
I would like to write tool for inserting steel sections. Because of lack of time I'm asking members of this forum to join my project.
Involvement forum members would be to write a function that creates polylines of cross-sections. I will make database of sections and DCL.
If you would like to join me then lets go :)
First example I-Profiles according to DIN-1025-1:1995:
Given data:
h | bf | tw | tf | R | R1 | slope (always 14%)
Example of pline based on data above in jpg file.
Example data I140 (in mm)
h 140
bf 66
tw 5,7
tf 8,6
R 5,7
R1 3,4
Slope 14

Since the dimensions are predefined, this seems like an ideal application for the use of dynamic blocks.

AutoCAD Architectural already has all the steel shapes in they Detail Components Tool, including decking, bar joist ect.
I will stay there are a lot of Code out there that has been done for which you can modify to suit your needs.

I'd suggest creating point list for the 1/4 of the steel shape. Then reflect (mirror) the point list on one axis and redefine the point list, then reflect again the point list on the second axis and redefine it again. Finally for each point create list of group codes like:
_$ (80.0 120.0 0.0)
'( (10 80.0 120.0) (40 . 0.0) (41 . 0.0) (42 . 0.0) (91 . 0) )
Append them for LWpoly elist and entmake it.

Thank you all for replies

For many reasons this is not good solution.

Amazing tool but unfortunately code isn't open and this is not free tool - no use for me

I'm using Advance steel so I also have a lot of steel shapes, but users of pure Autocad don't have tools like that.
I downloaded a lot of code which is out there and of course i will work with that.

I will check this one, thanks CAB

This is also my idea.
In conclusion,
Idea of this post was to get help and write tool as community, I will write this sooner or later by myself but it will take a lot of time (no free time - dad soon :) )
Thank you all - I will be posting all progress :)

Such as?
for ease of handling, extending, trimming, changing linetype of, region modeling for composite shape analysis, and converting to 3d solid and 3d surface etc.
Second main reason is that cheap Autocad brothers don't handle dynamic blocks very well :)

Like master_shake do not reinvent the shape, another if not mentioned "AlsSteelMill.zip"

Your drawing steelsections do you need the next step which includes the shapes like "Strucplus" does all the member connections as well plus way more.
