Lisp routine for spacing blocks

Hello Everyone,

I am looking for a LISP routine which user defines an area (rectangle) and a blocks and 2 numbers x & y (array dimension) and the the routine place the amount of blocks inside the rectangle.

NB: the distance of block-edge of rectangle shall be distance of block-block divided by 2.

I need to use this routine to place for me the lighting fixtures. lights must be away from walls half distance of light to light.

Thank you experts.

There is a lot more to this but its not hard you need to define the rules ok a light is half a light from edge but which light ? How big is it in X & Y etc. A down light at 1.2m c-c a flouro is already 1.2m long at 2.4m spacing and so on.

You can use array or a double repeat loop. Basic lisp code.

Me I would search a bit harder its already out there, hard part is finding the search criteria.

Thank you for your reply BIGAL.

Yeah, I got your point, but the routine which i am looking for will get the distance from center to center. it will measure the rectangle and then will divide it to the number x or y.

for the time being i am using divide function, but it takes me a lot of time.

I am working now on a huge project and i am new to lisp programming, that's why i am seeking help.
