I have made a lisp routine to draw lines on polyline. And here are a lot of lines on it. So using comand
"(command "line" pt1 pt2 " ")"
takes a lot of time. Is here a way to creat lines in memory or similar and only then draw them all on screen?
I have search but coudin't find any info. I do not know how to formulate a query.
I have drawings with a lot of polyline objects. I need a routine which will draw multilines by coordinates of vertexes of this polylines. For example, if there is a pline with coordinates 10,10 - 20,20 i want to draw in other layer MLINE with the same coordinates. I know it's should be simple but can not gues how to do it. I've never used LISP before.

is there a way to draw a polyline and have autocad clip everything outside of that polyline and discard it so that i end up with a smaller drawing. only the information in that polyline, nothing outside of the polyline

I have not drawn text or inserted blocks programatically before where the plane they lie on is not flat.
I have done it before by setting a ucs and drawing stuff, but now I want no switches of UCS involved.

View 8 Replies View RelatedI've written my first little Lisp function.What it's for is drawing a simple borehole profile that can then be used to draw stylized cross sections on top of it.
Upon start the lisp, pick a point on screen (to get the X coordinate [x1 below]), then enter ground level at the command line [g1 below], then enter as many thicknesses as are present in the borehole log (will vary, but typically between 3-12). These I added to a list, because that seemed to make sense when I did it.
What I want it to do then is draw a pline from x1, g1 down to the next point (x1,g1 minus the 1st thickness), then the next (x1,g1 minus the 2nd thickness) etc., to the bottom of the borehole.
Then my CAD guys can sit there, and using the borehole logs, enter the values of the boreholes and it draws them on the screen, making it easy to join th dots.
It might be good if it placed a Acad point at each point as well, but I'm not overly bothered about that at the minute.
Here's my attempt so far.
(prompt "Type 'e1' to run...")
(defun c:e1 ( / )
(command "graphscr") (setq x1 (getpoint "
Pick insertion point:")) (setq x1a (car x1))

I would like to be able to draw squares by the area they should have. So that if I need a square of 50m2 autocad automatically draws a square of sqrt(50) x sqrt(50)
Because right now I have to draw 200 squares with 100 different areas and I have to calculate and manually draw each one of them.
i need a vlisp program to draw polyline between two blocks.

The problem is when I try to draw a bounding box around an object while in another UCS. It seems that it always draws the bounding box at the WCS instead of my UCS. I have used (trans <pointlist> 0 1) on all combinations it seems and I still cannot get it to draw the bounding box at the current UCS.

In the front of my drawings i have a view tables. in the second column stays a code that represent a location.
e.g. LVC stays for Low voltage cubicle. Now it is my intention to substitute these code to the description of code in one time and only the second column. The several descriptions are written in an .txt file, like LVC;Low voltage cubicle and on the next row LVP;Low voltage panel, and so on.
I think it is only possible with Lisp? or there are other way?
In the past i did it one by one, because mostly there where 2 or 3 tables, now i have a big project with more than 20 tables.
Can a AutoLISP command be written to read an attribute in a block and draw a circle with the attribute as the diameter using variables? The appilcation is taking the diameter of a tree trunk (the attribute), multipling by 12, and drawing the canopy circle on hundreds of those blocks. So the circles drawn will vary in size.
Not sure how this could be set up, i'm not familiar with LISP writing at all.
1) Read block, single, mulitple or definition?
2) Read Attribute
3) Varaible of attribute, (attribute is an inch measurement...it needs to be multipled by 12 to get feet for final use as circle diameter drawn)
4) Draw circle, variable, with diameter coming from attribute variable (attribute in inches that is multipled by 12)
5) Center point or circle to be block's base point
I have to put some trusts between two beam. It sounds easy but i'm unable to handle the divide and round off commands in the lisp. See attachement also.
To draw my trust between the 2 beams, what I normally do, is that I manually take the distance between the two points say it's 10 000 and wrote it down. Then I divide it by my max gap, say 1200, it is the max space between trust.
10 000/1200 = 8.333333 that's the result of how much trust and space between them that i'll need, 8 trusts, 9 spaces between the 2 beams. (That is what I'm unable to do in the lisp, tell it to round off 8.333 to 9 and use 9 for divide command)
What I manually do at this point to draw these trust is that I must create a temporarly line between the 2 beams, perpendicularly to these and divide it by 9.
It gives me 8 cross (or point) to draw my trusts. All this is long to do manually because I have many bay in building and I have to redo this operation for every the bay.
So, what I would like the lisp to ask is:
Specify distance between two beams (Between where and where) :
Specify the lenght of the trust :
Specify max gap: I would like to answer a number here, say like 1200 max
(The lisp should draw the lines on the current layer, color and linetype of the current layer and not draw a line at the beginning and at the end because that's where my Beams are. I hoped you understand, see attachement.

I need to draw an ellipse at a specific point on a drawing.

I do a lot of repetitive tasks in my daily drawings and I’d like to make life easier! I was researching how I could write a lisp to draw a walkway path for a roof. I came across a couple of interesting posts but couldn’t follow the code because of my lack of understanding the language.
So what I do is draw a 30” x 30” square (using the rectangle command). Then copy it so there is a 2” gap between them. Then I go back and hatch them with a dot hatch scaled to 96. What I’d like to do is type a command and it would draw the walkways for me and hatch them if possible. The problem is the last one is a custom cut size depending on the length of the walkway run?
Now I know I can draw a line, draw the square, hatch the square, array it on the path with set distance between items, then fix the last one so it looks the way I want it to, and then delete the line. But why do all that when I have a program that allows me to customize it to be done for me?
i am writing something that will draw consecutive lines with a rubberband to be used as a leader from a block's insertion point. this:
(WHILE
(SETQ LN (GETPOINT "
Select Next Point (ENTER to Finish) : "))
(COMMAND "LINE" (GETVAR "LASTPOINT") LN "")
)
works, but does not include the rubber band. i tried:
(WHILE
(SETQ LP (GETVAR "LASTPOINT"))
(SETQ LN (GETPOINT LP "
Select Next Point (ENTER to Finish) : "))
(COMMAND "LINE" LP LN "")
)
which includes the rubberband, but will not exit the loop. The last break source in VLIDE shows that
(GETPOINT LP "
Select Next Point (ENTER to Finish) : ") is casuing an error. Placing
(SETQ LP (GETVAR "LASTPOINT"))
outside the loop causes all lines to be drawn from the same point rather than the endpoint of the previous line.

This is to trim a line that crosses another. I draw lots of plumbing plans. It draws a circle based on 'dimscale', trims a line to that circle, then erases the circle. The problem is if you miss the trim point (PT2) it does not erase the circle and you lose your object snaps.
