AutoCAD Visual LISP / AutoLISP :: Rounding Up Block Coordinates (insertion Point)
Sep 2, 2013
We have several AutoCAD drawings with hundreds of block references inserted with imprecise coordinates. Now we need to dimension all elements and need to correct these positions.
I am searching for a routine to round these positions up or down towards a 5mm precision so I don't have to manually move every single block element.
Is there any way to automate the task or do you know any workaround (like inserting the elements into a drawing with poorer unit precision settings)?

How can I find a block with a specific name and get what the coordinates are? What we have is our Bill of Material is attributed blocks. I am attempting to change the first one. Well all of the lines that list the parts are seperate blocks with the same name. Now the Top Line of the Bill of Material is a different named block. If I can find the coordinates of this block I can then select the first line to do what I need to.
If needed: AutoCAD 2013 User using Visual LISP for editing LISP and DCL files Also I have AutoCAD 2011 currently still available for us, but we are using AutoCAD 2013 for 99.9% of AutoCAD use

I have insert blocks in my dwg. It is the circle. While creating the block, i was just pick the point into the circle not exactly at the centre.
Now i want change the insertion point of the block at centre of the circle without moving the objects from the dwg.
Beacuse i had use block editor to change the insertion point. But after changing, all blocks were moved from the original position.

I've have code to test if the insertion point is within a closed polygon. But prior to testing the insertion point I use ssget to trim the selection set initially..
(ssget "CW" Pnt_List (list (cons 0 "INSERT")(cons 2 BlockName)))
this requires that the whole Crossing Polygon is visible, so I do a zoom first. This requires time. Is there a way I can do this that does not require the zoom?

Create a routine that looks for a block based on a portion of that block name, using a specified path or search path.
For example, block to search for is BLOCKABC123, so if someone inputs ABC or 123 as a block name, it will locate that block within that folder and inserts it into the drawing at a user specified location.
Ideally, if there is a check in that if it finds more than one match, then perhaps it flags or prompts you to choose 1, 2, or 3 option which block to use. But I can live without this special function if it requires too much time to code.

How do I change the insertion point of a text using "vla-put" ? I've tried using :
(vla-put-InsertionPoint en a)) with a = (4455.94 428.576 0.0)
and I get the following error:
lisp value has no coercion to VARIANT with this type: (4455.94 428.576 0.0)

We have been modifying a trim-around-block routine to have as few clicks as possible and though it feels like we'd be able to have the line to be broken auto-selected based off of the insertionpoint that was set as a variable.
;(setq pnt1 (getvar "lastpoint")
; sst1 (osnap pnt1 "nea")
;end setq
;(setq ss (ssget '((0 . "LWPOLYLINE")))) ; limited to Polylines
; (while (> (sslength ss) 0) ; as long as there's anything in [or remaining in] the selection set))
; (setq ent (ssname ss 0)
; paramcount 1
; ) ; first entity in [or remaining in] the selection set paramcount 1); end setq
are about the closest snippets of code that we've managed to find but neither of these are working.
How we can force the program to break the line without the user having to select the line (because they will have already selected the insertpoint, and using osnap nearest would find the line that requires breaking)

I need a function that accepts a block name as an argument and will insert the named block without fail no matter if the block was made to scale uniformly or not.
How can I determine if the block should be inserted like:
(command "-INSERT" blkn "0,0" 1 0)
or:
(command "-INSERT" blkn "0,0" 1 1 0)

wondering if is possible to have a lisp routine to:After use the INSERT command, the routine will automatically change the layer of the inserted block to a specific layer according of its name.
i.e.
Step 1 : I will insert a block named Block A using the normal autocad INSERT command (I do not want to insert the block without the Insert window dialog box)
Step 2 : After the insertion, the routine will select the last insertion (or the last object, or any other best way to select this block and will take it's name)
Step 3 : The routine has a list that says:
(If the last insertion (or object) is named Block A, put it in the layer Layer A with color Bylayer and linetype Bylayer)
(If the last insertion (or object) is named Block B, put it in the layer Layer B with color Bylayer and linetype Bylayer)
and so on... I can make the approprieated list by myself folowing my standards.
I think it will be nice to avoid an error if the block is not in the list. So:
(If the last insertion (or object) name is not in the list, do nothing)
To finish, it will be nice to create the layer if it does not exist. Also, Unlock, Thaw and Turn on the layer if it's Locked, Frozen or Off.

I have a drawing with various layouts that when I do a Zoom Extents the drawings is reduced to the size of a point.
I have done all the usual, ie: look for extra entities that are "out in space" so to speak and there are none.
I wonder if I have a block or image which may have an insertion point "out in space" and if this may be the issue.
Is there some way to Select all entities or Blocks (insertion point) that may exist outside a particular area ie: drawing limits.

Is there a way to modify the text insertion point of multileaders using lisp? We have a problem with some of our multileaders getting a landing distance set to a negative value. My lisp routine will correct these to a default value, but then the text jumps a bit. If I could get the insertion point prior to changing the landing distance then I could restore that point after changing the landing distance.

I am learning autolips and i found a problem that i can´t solved.
(vl-load-com)(defun c:pmb ( / ss ent pt )(prompt "
selec block : ")(setq ss (ssget '((0 . "INSERT")))) (setq ent (ssname ss 0)), (setq pt (cdr (assoc 10 (entget ent)))) (command "point" pt))
wich this code you select one block and insert one point at insert point´s block.
which this other code yo select all block and insert all point.... but in one block
(vl-load-com) (defun c:pmb11 ( / sele cod bloque nbloque lista pt ) (prompt "
block: ") (setq sele (ssget ( List'(0 . "INSERT"))) Cod 0 )cod (1+ cod) (repeat (sslength sele) (setq bloque (ssname sele cod)) (setq pt (cdr (assoc 10 ( entget bloque)))) (command "punto" pt) );repeat )

know a lisp routine that would insert a block @ a specific point on an arc? For instance if I have an arc that has a radius of 20'-0" & I want to insert a block at a set distance from the end of the arc.i could probably use the divide or measure command but I was hoping I could do it with lisp. I would also like to be able to move the object along the path of the arc at a specific distance.

I need a routine that inserts a point at the insert point or block named "Insert_Point" at every block in the file. The routine could use the current layer, which would be set prior to starting the routine. If it could request the user for the PDMode value and PDSize that would be great too. This will assist me in creating block libraries.

I would like to create a lisp that places a block at a pre-calculated point. I've created a lisp that fetches me a block to place into my drawing. The only thing is
I have to point out the place i want it to go. I want it to got into the corner by it self. I would like to create a lisp that calculates, by the retrieved variable of the layout / paperspace, minus 10
from the bottom right corner. minus 10 from the bottom up and from the right edge to the left.

How would I go about this. if a two blocks or polygons are overlapping area?
A good method or the algebraic formula for a function to tell me if a point is inside a polygon or block's area?

I have a lisp routine that I would like to add to. Right now when running the macro the user is not prompted to "Pick Point On Line" in this example
(command "insert" blk "s" var1 pause pause))
I have added the line
(setq pt1 (entsel "Pick Point On Line "))
(command "insert" blk pt1 "s" var1 pause pause))
but the command doesn't seem to like my PT1 value
BLK and VAR1 are set in another lisp routine.

I'd like to create a lisp that would check my drawings for stray vertices (I only draw in full measurements per UCS), and automatically round them up to the closest whole value, or at least mark them up in circles for manually fixing them.

For a program i am working for i have to extract the base point of a dynamic block.
This can be done perfectly by this function:
(cdr (assoc 10 (entget (car (entsel)))))
But i want the entity selected based on a previous slected point. So for example when i selected pt1 (which is a point at the border of the dynamic block) i want to be able to extract the base point on the block whit this point.

trying to insert point instead of block.
(setq blok (entget (car (entsel))))
(setq point (cdr (assoc 10 blok)))
(setq XX (rtos (car point) 2 20)) ;; x koordinata bloka
(setq YY (rtos (cadr point) 2 20)) ;; y koordinata bloka
(setq ZZ (rtos (caddr point) 2 20)) ;; z koordinata bloka
(command "point" xx,yy,zz) is not working
!xx="5582453.414999999" but when i (atoi xx) i get 5582453 no dedimals...
how to create valid insertation point from xx, yy and zz?

would like to set a base point during insertion of one block.When not insert by AutoLISP, just type "b" to be able to change the base point.
But when I'm using an AutoLISP that inserts a block, it does not work, it interrupts the sequence of routine.
Lisp:
(defun c:carrobox()(setq #clayer (getvar "clayer")) (if (= unidades nil)(setq unidades "cm")).....

I am looking for a method to export all the GPS coordinates which have been assigned to each point along with the properties of that point to an excel csv. In our drawings, there are multiple columns and each column has four points and each point has X,Y,Z coordinates. I want to export all this information to an excel sheet.

I want to get the minimum and maximum x, y coordinate values of selected lines. In other words, i want to find the top, bottom, left and right edges of a set of lines.
Is it possible to achieve this with a lisp code?

I'm writing function which will facilitate user to offset dimension. After enter command, he select dimension and select point near one of dimension's arrowheads. Then I'm calculating new XLinePoint1 or XLinePoint2 and replacing original.
I have everything done. I thought ... The problem is when user firstly create AlignedDimension and after that he create RotatedDimension by using continous function. After that XLinePoint1 and XLinePoint2 are not parallel to the DimLinePoint (look at image).
How can I get coordinates of points selected in red rectangles?
I know that one is specified as "dimension line defining point" but what about second? How can I get its coordinates? Or maybe there is other way to get this point?
