timing

Hi!

 

How can I suspend the execution for a_time seconds/ or milliseconds?

 

Like in C : sleep 1000 --the program sleeps 1 sec

 

Thanks any help!

(defun delay1 ( msec )
 (command "_.delay" msec)
)

is probably the least CPU intensive, else something like:

 

(defun delay2 ( msec )
 (
   (lambda ( start )
     (while (< (- (getvar 'MILLISECS) start) msec))
   )
   (getvar 'MILLISECS)
 )
)

Thanks again the fast answer Lee!

You're welcome

(defun delay (d / cd);;;DELAY 1e-6 = 1 Second
 (setq cd (getvar "CDATE"))
 (while (> (+ cd d)
           (getvar "CDATE"))))

 

More of a kludge. -David

Hi!

 

I have another question:

How can I force AUTOCAD, to draw everything immediately.

Let me clear: If I make a loop: i.e. 100 times want to draw blocks, then Autocad will draw a group of blocks (10-20) and not each block.

So Autocad will draw 5-10 times 10-20 blocks, and not 100 times 1 block.

I'd like to draw each block immediately.

 

Thanks any help!

If speed is the problem, (entmake) is a lot faster than a (command). As to making multiple entities is a single operation, Autocad is not up to the task. There are MINSERTs which can be useful. They can only be used a rectangular arrays. -David

Thanks a lot!

 

Another problem:

How can I run parallel process in autolisp?

I hope it's capable of it!

(I mean parallel threads)

If you mean multitasking, then the short answer is 'No'. -David

Yep, that was what I wanted to know.

Thanks

Hi!

 

This problem belongs not really here, but I write it here:

 

I'd like to divide a LWPOLYLINE into points, they are a specific distance from each other.

 

So: I have to watch only the dxf code 10- which is the point coordinate and the 42 which is the buldge...

If the polyline phase is line then ok, that case is ok, but what can I do when the polzline next two points are a buldge.

 

I hope you understood me.

 

So I want a function like this:

(defun makepoly (polyline distance)

;;;

returns the list of points, which are in the polyline and from a distance of each other.

 

)

;when I mean distance, that means the distance ON the BULGE.

 

thanks any help!
