AutoCAD Visual LISP / AutoLISP :: Block Insertion Point Is Within A Closed Polyline
Oct 11, 2011
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..
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?
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
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)?
Is there a routine that I could use to count the blocks that are in a closed polyline? The blocks may have or not one or more attributes.
In a previous session I saw a routine which was counting the blocks which had attributes in them, but it doesn't really work, because some of the blocks dont have attributes.
Also is there a routine that counts the different texts that are in the same polyline?
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.
I've been using the admittedly pieced together code in order to insert border blocks around a closed polyline. Yhe problem I'm having is that when the Block angle is say "zero" the block is inserted the same way both on top and below the polyline. Since the blocks surround the polyline the blocks on the downside should have an additional 180 degree rotation. How to deduct that the portion of the polyline is in a certain quadrant and adjust the insertion angle as necc? I 'm not sure thats even the best approach.
Dim pso As PromptStringOptions = New PromptStringOptions("Enter name of block to create reference: ") Dim pr As PromptResult = myEd.GetString(pso) Dim blkName As String = pr.StringResult 'If (!bt.Has(blkName)) Then
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 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:
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.
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 writing a routine that will place a piece of text at a specified point along a polyline. My problem is to determine the angle for the text. It needs to be the same as the segment of the polyline that it falls on. Just can't get my head around how to get that angle?
I can get a list of the vertex point of the polyline, but how do I determine the segment the point falls on?
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
I'd like to set up a blockwith different attributes like Roomname, Floor, Area,...
Therefore I'd like to link a polyline of the drawing with the block and it shows me its area. I know how it works with fields, but not how to connect it when the field is within a block.
I am starting with a polyline then i use the pasteblock command to insert that polyline as a block.Now i can pull up the property box and change the xyz scale.
I would like to know how to change these setting in my lisp.The scale will be x=1 y=0.1 z=1
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.
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.
