Architectural Lisps - Free for Download
Warning Imperialists! These are METRIC routines, ie they only use millimetres. As with a lot of lisp files, you must have your support directory pointing to where you have put your files. I would suggest creating a directory structure as follows: c:\cad\lisp for the lisp files-eg truss.lsp and truss.dcl c:\cad\library\architectural\components for the contents of the Components folder c:\cad\library\architectural\wood ends for the contents of the Wood Ends folder All of the above locations should be added to the Autocad support directory. To add your directory to the path, in Autocad go Tools/Options/Files Tab/Support Directories, and add it in there-you need to hit ADD then BROWSE.Truss.lsp: The truss routine uses a dialog box called truss.dcl to draw a cross-sectional view of a roof truss. It inserts components such as GutterCopper in the process of drawing the truss. The process is type in Truss (after loading the routine), and a dialog box should appear. Please bear in mind this has been designed in New Zealand and may not put in expected standards of other countries. Wood Ends is just a collection of cross-sections of common (in New Zealand) wood sizes. It could be argued that the bracing is a bit unrealistic. This is usually not a problem in New Zealand because the draftsman is only expected to produce an approximation as the actual truss is redrawn anyway by the truss maker.
Wind.lsp is a rough and ready method for drawing windows in 3D. It can only do a single sash or a series of sashes, horizontally. The nice thing about it is that it puts the frame on a layer called "Window" and the glass on a layer called "Glass". You need to be in a southeast iso view of a solid wall with a hole already in it to get it to go, as it will ask for a series of points, the, bottom left corner, the bottom right corner and so on. Keep an eye on the command line! Lab.lsp is for doing the labelling of the rooms of a house. Most people (me included) just import a block containing all the typical text they need, then explode it and drag the text to where it is required. This routine is probably slightly faster as you just type a letter, for example D for dining, pick a point and there it is. It senses the dimscale to know how high to make the letters.
Wooden Joinery Lisps is a collection of lisps for drawing a wooden window-otherwise known as "millwork" in the USA. The Instructions are in the ZIP file. The first thing to do is draw the frame, then any transoms, then any mullions, then finally the sashes. It is not completely bug free, but then again, it is free! It has a very crude command line interface. The idea is that if someone uses it, likes it and has a bit of money for development, then I could be persuaded to make it more user friendly, bug free etc. You need 2 zips to download for this- * Wooden Joinery Lisps and * Profiles Click on the links below to download files.
