Autocad Contour Lisp
Sep 15, 2005 - AutoLISP can form an intermediate contour that assumes a linear. LSP files from Cadalyst's CAD Tips site and save them in AutoCAD's. This really shows the great convenience of using the more modern approach to LISP.
Free Lisp Routines for AutoCAD and CorelCAD Free Lisp Routines for AutoCAD and CorelCAD Please find below a list of CAD lisp routines which I have written to automate common UK road design tasks when using CAD programs such as AutoCAD or CorelCAD These free lisp routines were tested using which accepts AutoLisp. Therefore I assume these lisp routines will also work on AutoCAD, but as I don't have access to AutoCAD I cannot confirm this You're welcome to download, use, copy, amend, and adapt these files, but at your own risk. I offer no support should these routines or commands not function as you expect. However, please feel free to leave constructive comments (see foot of webpage) and suggested improvements. I've checked these files for typing mistakes, but I suspect there's still some errors I haven't found yet Beyond the table below, each command is explained in more detail (click on the command names to scroll down this webpage) Lisp files Commands Description (right click and select 'Save target as.'

It was written for Autocad 2000, so there's no guarantee it will work for your version. Supports any version. Download a free trial here. See Lisp Notes below ------------------------------------- Unzip files to /support directory or any directory in program search path.

Option 1 imports any xyz comma separated point file onto layer 'CTL_PNT' or writes any selected points on layer 'CTL_PNT' or 'CTL_PTMP' to a comma separated point file and deletes all selected points from the drawing. If you read a file, it will erase any existing points on layer 'CTL_PTMP' and change any existing points on layer 'CTL_PNT' to layer 'CTL_PTMP. The point files can have white spaces, but no tab characters or blank lines. Option 2 creates a triangulated surface from all points found on layer 'CTL_PNT'. It will prompt you to check for duplicate points. It can take a while to check if you have thousands of points, but the program will hang if you don't delete them first. Option 2 calculates all triangle points and takes an average of all long side horizontal lengths.
You can ignore this value and create all triangles, or enter a factor to delete any triangle with sides longer than the average times a factor from 1.5 to 5.0. You can either ignore this option or use it to delete most of the extraneous triangle faces that shouldn't be there. It always deletes any previous triangles, so can keep trying different factors to get the surface the the way you want. If you need to change a space separated point file to a comma separated file, try one of these command line programs. 32 bit version (142,848 bytes) or 16 bit version (18,600 bytes) (8 char file names only.) Option 3 creates contours by drawing plines thru each triangle surface on temporary layers. It selects all lines on each elevation, joins them and asks if you want to create spline fit curves. Spline curves take up a huge amount of drawing space and lose accuracy on sharp corners if enough points are not supplied. If successfully joined/splined, it changes each contour to layer CTL_CONT and deletes all temporary layers. Option 4 switches to a front view, uses the latest contour spacing with the left and right limits to select and color contours.
It uses a crossing window to select the contours, so make sure your drawing limits don't exceed the limits of the objects by some huge distance. If you open a drawing and run this routine before you create any contours, it will check if there's any surface on layer CTL_TIN to find hi and low points. If not, it will ask you to supply both numbers in integer values. Anything above and below what you're coloring will work. It then asks you to pick an entity on the layer you want to color and the vertical spacing you want to use. Option 5 annotates by picking a point on any contour line. It will prompt to either break the contour line or place the text above the line.
In screen resolution no second screen is detected, and even switching to a VGA output does not change anything, neither does selecting any of the projector options, or changing to the lowest resolution of 800*600.
