Description: Draws profiles of steel shapes

Installation

1. copy all the STL*.* files to an AutoCAD support directory
2. Appload the STL.lsp file
3. Type STL_AUS for the Australian Pallet 
4. Type STL_USA for the USA Pallet

Licence
- Open source program, If this program saves you time, please show your appreciation by sending me some money.
- Please email this program if you make improvements.

About the Program

- I have built this program on the AutoCAD 2000 platform, but it should work on other versions.
- All closed shapes are drawn with polylines. 
- Insert points are; Top of beam center, top of tube center, pipe or tube center, 
  Angle heel, channel heel, and middle purlin web. 
- Shape contours are drawn accurately with tapered flanges and radii used on corners and edges. 
- The program sets an automatic "osmode" setting of "111" (intersection, endpoint, midpoint, centerpoint, node, and 
  insertion) to aid in selecting insert point, automatic re-set to "0" for drawing the shape, then reset to original 
  osmode of drawing environment. 
- Insert prompt has a reference option. This allows placement of insert point by "picking" a base point and then entering 
  its x,y reference to the "picked" base point. 
- Imperial structural shapes, pipe, and tube listed in the American institute of steel construction's (aisc) steel 
  Construction manual, either the ASD ninth edition or the LRFD first edition. 
- Metric dimensions are from the "BHP Hot rolled structural products 1998 edition" and the "Stramit purlins girts and 
  bridging, 2000 edition". 
- For 2d top and 3d side views the ucs is automatically reset to world. It does not work if it is UCS.
- If hidden linetype is not loaded, the program will attempt to load "hidden" from the default .lin file
- lines are drawn to the current layer and color setting.

Credit where credit is due
 
This program was inspired by 3 other similar programs, that each embodied 
portions of the functionality of this program;
  - stl.lsp version 1.1 by Allan Rogers
  - steel.lsp by Jeffrey David Wells 
  - Beam.lsp Version 1.0 by Steve Q. Stapleton, modified by Bill Le Couteur.

To do list 

- Add metric Welded beam and Welded columns 
- Show dimensions of Z and C purlins on the dialog box -
- Add metric Universal Bearing Piles 
- Add metric BT and CT tees 
- Add metric taper flange channels 
- Add metric taper flange beams 
- Layer and color controls 
- Formed angle without the radius, for extruded shapes. 
- Formed angle with adjustable leg angle. example not 90 deg, 45 
- End shapes as blocks option. 
- Hatch end shapes option. 
- EMAIL me your suggestions. 

Enjoy.
