Thank you all for replies
Since the dimensions are predefined, this seems like an ideal application for the use of dynamic blocks.
For many reasons this is not good solution.
There is also this:
Amazing tool but unfortunately code isn't open and this is not free tool - no use for me
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'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.
Another thread on the subject.
I will check this one, thanks CAB
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)Append them for LWpoly elist and entmake it.
'( (10 80.0 120.0) (40 . 0.0) (41 . 0.0) (42 . 0.0) (91 . 0) )
This is also my idea.
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
