    MASS PROP

    if your looking for a lisp that allows you to select a solid or group of solids then report the weight and center of gravity, then this is your lisp for autocad 2000 and up ;This program draws a point at the centroid of a ;region or solid. The point is drawn on the current ;layer at the...

    lower left origin

    What I'm looking for is code that will allow me to select the object to be dimensioned with a pick box and it will find the lower left x,y,z coordinate by tracking the extreme edges to a theoretical intersection, set the origin to 0,0,0 at that point, and then dimension the part using the qdim...

    lower left origin

    What I'm trying to do is dimension parts using the ordinate method. In order to do that, I need to establish o,o in the lower left corner of the part so that my ordinate dims start from that corner. But sometime there isn't a convenient corner in the lower left (ie. a filleted corner) and I have...

    lower left origin

    I'm looking for a simple code that will locate the origin of a window selected object at the lower left so that I can quickly diminsion that selection using the qdim ordinate method. I am wasting too much time creating this origin manually and would prefer to include it in the code for the...

    MDT object enabler does not allow saving back

    When I open a drawing created by MDT6 using AutoCAD 2002 and try to save it as another filename, I get the following prompt "MDT object enabler does not allow saving back", even when I try to wblock out. Does anyone know how to resolve this problem?

    3D Shading + Plotting

    This subject has puzzled me for years. Why would Autocad not provide the ability to plot a rendered image yet allow plotting of inserted raster images. The solutions above are good, but to make life a little easier, I just "Ctrl-printscreen" and "past-special" back into...

    dimensions & formulas

    No, That's not it. I want to insert an actual mathematical equation that would drive the text output.

    How to change density of blocks

    Try this code. It won't allow you to assign different mass properties, but it will report them. Currently this lisp only report carbon steel, stainless steel, & aluminum. UHMW. Neoprene, & pine will be added soon. If anyone wants to take a stab at creating a dialog for this, I would be...

    burn templates

    I need a better way to create burn templates. Currently, i use the wblock command and add .dxf to the file name so that our pattern torches will recognize the file. I have to manually "z" move to elevation 0, elliminate overlaps, and convert to primitives. What I'm looking for is code...

    dimensions & formulas

    Does anyone know how to add variables to dimensions that dynamically update with the association? (ie. if a dimension needs to show a value of actual length + 1/10 of actual length, how would I enter the formula <>+(<>/10) and get it to work?)

    draw a composite c.g. point and report massprop

    we have solved the problem and I've included the correct code for everyone. However, since we use an alert box instead of a dialog box, we are limited to 4 outputs. Any revision to this code to use a dialog box is greatly appreciated. (defun c:CG (/ ss mprfile title c-steel s-steel alumn UHMW )...

    draw a composite c.g. point and report massprop

    We are upgrading from AutoCAD r14 to 2002 and we have found that some of our lisp routines won't work. here is a lisp that draws a node at the centroid of a solid or region and reports the weight in Carbon steel, Stainless steel, & Aluminum. Does anyone know what is causing it to fail at the...
