I work with AutoCAD and do quite a bit of development in it useing Autolisp.
However I have come accross a situation for which I am unable to create the code that I need.? I think this code may need to be written in ObjectARX within AutoCAD.? However I am open to other solutions if another interface proves to be more suitable for the function.
I need a function for the purpose of creating a cutter path.? I do not want the function to create the entire cutter path, basically I would like to write my own routine that will utilize this new function, and create the cutter path from this new information returned. I would like to specify the x, and y coordinates over the top of contoured surfaces, (and/or? a solid if possible)? and have the routine return a point above the surface that is a
"minimum" distance from all the selected surfaces (or solid)...
In other words picture a ball nose cutter - basically a spherical shape,
that has to follow along a path in x, y and z such that it does not? violate
any surfaces... It can not just be a specific distance straight up, because
as the cutter approaches walls, or if the surface has any incline then there
is gouging happening....
I have tried and searched and can not find any good way through lisp.
I would be willing to pay someone to do it if its not to large a project.
This routine would have to be fast because the routine (from lisp) will need
to specifiy the x and y points every 0.001 or to 0.010" and step over a part
to be machined in as little as 0.005" wide "rows".? in other words, for a
part that is lets say 3" x 6" there could be 1000's or maybe 100,000 points
to check very quickly.
Perhaps more needs to be done in object arx to attain the speed, that part I
do not know....
Thanks for any thoughts you might have.
We will have to work on more specific requirements as we go.
p.s. Yes I know I can go out and buy CAM systems, this is for a custom
application that I must integrate.
Thanks in advance for any thoughts on the subject!
