View 1 RepliesI have many drawings with blocks containing polylines set with property Fit/Smooth = cubic. For conversion purposes, I need to change them to FIt/Smooth = none. It is easy with the Properties palette but, because I have lots of drawings to fix, I want to write a lisp routine. Any VLA-SET-xxx property that will allow me to do it in lisp?

This is what i would like to make a lisp for: if the user gives the number tree the last tree inserted entity's are deleted. If the user gives the number four the last four inserted entity's are deleted.
View 2 Replies View RelatedI know through the block command you can write out a selection of entities to a single drawing.But what I am wondering is if it is possible to have two drawings open, and transfer data quickly between the two?
As an example as we are detailing an assembly we create a title block around a detail, put dimensions and notes on as needed and would then like that to be transfered into another drawing next to the previously transfered detail drawing.
I want to code this lisp. The problem which I face is, In some drawings which come from the client, there are a lot of blocks.
I want to detect the blocks which has no sub-entities (but attribute) and add a rectangle inside this block, If it is an attribute add a line from 0,0, to insertpoint of attribute.
Is it possible to write an AutoLISP script to read an .xlsx file and use the data in the various cells to modify a block within a .dwg?
Ex.: We use Flow Control Modules (FCMs) and use AutoCAD Electrical to show electrical contractors where/how to wire up the devices. In AutoCAD, we have blocks for various types of FCMs, and each block has terminals which are tagged DESCA1, DESCA2, DESCA3, etc. Each of these tags will change based on what the particular FCM is used for.
We also have .xls(x) files we call FCM Maps, which come from our engineers and tell the drafters how to lay out the .dwg files.
Is it possible to write a LISP script to take, say, cell A1 from the .xlsx file, and put that data into DESCA2 in the block, cell A2 into DESCA3, and so on?
I am having nearly 1000 drawings where I need to change the title block in a new format.
I am stuck up in moving all the entities in cordinates 15,280 (upper point) and 205,55 (lower Point) to 275,294 (upper point and correspoing lower point.
I have 2 selection sets and I'm looking for a more elegant method of checking if both sets contain the exact same entities (note - the order of entities might be different).

I have redined AutoCAD's copy command alias to C, but to also do other things, like set a few important variables in the background. One of the lisps I've incororated are making new viewports, that also create layers that are visibly specific to the viewport being created.
We were tasked a while ago to do an easy job of copying entities (dimensions, text and what not) in a layout. The problem is, users are copying the viewports too, which is bit more ineffificent than using the create viewport command I developed.
Is there a way to see if a selection set includes (0 . "VIEWPORT") entities? If the check returns nil, well then all is good. If the check returns "true", then I can prompt the user that a "VIEWPORT" entity is selected. I can then exit the command, or ask the user if they are sure they want to copy the "VIEWPORT" entity.
I have a lisp that draws variety of entities such as lines, arcs, hatches, points, blocks, text etc. How can I make one single block containing all of them, i.e. one block that has all items drawn since the lisp was invoked.
View 8 Replies View RelatedI have a CAD file with a couple hundred detail blocks in it, and I am trying to standardize them without haing to block edit each detail block.
What i am trying to do in each block is as follows:
- Explode all dimensions, leaders, and blocks
- Change all objects to layer "0"
- Change all lineweights to default
- Change all object on colors 7 and bylayer to byblock
- Change all text and mtext to arial font

I have code that will set and sae a current UCS to the front of an entity, of course, depending on the viewpoint. This is so, because we need all draft lines in front of 3D solids, such as dimensions, leaders for labels, text entities and so on (the reason for not putting these entities in paper space is another discussion ).
But I'll have on of two problems on numerous occasions:
1. The user forgets all together to run the command.
2. The user will pick the wrong entity that is in the foremost position in that view.
The code I have utilizes the following:
(setq ent (car (entsel)))
(vl-load-com)
(setq obj (vlax-ename->vla-object ent))
(vla-getboundingbox obj 'LowerCorner 'UpperCorner)
(setq LowerC (vlax-safearray->list LowerCorner))
(setq UpperC (vlax-safearray->list UpperCorner))
Then I'll analyze the X, Y and Z of both the lower and upper corners, and set my UCS to whatever is proper.
Is there a "LowerCorner" and an "UpperCorner" for all entities. I can't see "VSMIN" and VSMAX" working because the elevation of the returned coordinates is always "0,0"
I have a lisp routing that the user has to use, to create a ucs, that is exactly on the front of the entity the user selects, so that whne they are drafting, labeling, dimensioningn the 3D entity, none of the drating lines are hidden when plotted.
The code is as follows:
(setq obj (vlax-ename->vla-object ent))
(vla-getboundingbox obj 'LowerCorner 'UpperCorner)
(setq LowerC (vlax-safearray->list LowerCorner))
(setq UpperC (vlax-safearray->list UpperCorner))
[code]...
Then I do a condition to see which points are greater than others, and move the ucs depending on the view to the foremost point. The program works perfectly.... however, often, they forget to use it.
I was wondering if I could incorporate it in another lisp that everyone uses, but not having the user pick the entity they want to be in front of (sometimes they pick the wrong entity). Instead, take the group of entities (anywhere between 1 to 30 per drawing (these are piping spools, so the entity count is not that great in model space)) and set a front working plane in model space. Working in paperspace is not an option, we're just too deep into our templates and processes.
I know there is a vmin and vmax, but they are for the X and Y axis, a VMax along the Z-axis would be great.
I am modifying stuff in a dynamic block insert entity. There is no "endblk" entity at the end of these definitions and I need to cycle through every entity within the block definition. When it gets to the last entity, I get an error because you cannot entnext passed the last entity. There are 2 things:
1. How to retrieve the # of entities in a block without cycling through it.
Or
2. A quick lesson in the *error* function, I cannot figure out how to implement this. I basically want to to say:
(if (entnext myent)) returns a error, don't abort & continue on.
I am trying to create a selection set (or LIST) of all objects inside a unnamed GROUP.
I found a means to access the unnamed group, however I am having trouble creating the list.
Command: (entget (cdr (assoc 350 (dictsearch (namedobjdict) "ACAD_GROUP"))))((-1 . <Entity name: 7efe6280>) (0 . "GROUP") (5 . "130") (102 . "{ACAD_REACTORS")(330 . <Entity name: 7efe5c68>) (102 . "}") (330 . <Entity name: 7efe5c68>) (100 . "AcDbGroup") (300 . "") (70 . 1) (71 . 1) (340 . <Entity name: 7efe6268>) (340 . <Entity name: 7efe6260>))
In the example above, there are 2 entities in the group.
What I want to do is to remove a certain entity from the GROUP, then delete the entity.
Repeat until all entities of that type are removed (I can figure this part out...).
How do I create a Selection Set (or LIST) of all entities inside a GROUP?
To access the first GROUP name in the dictionary:
(cdr (assoc 3 (dictsearch (namedobjdict) "ACAD_GROUP")))
I am working on a flood inundation, I would like to find a lisp or command(i'm not finding) to connect two points with a given elevation following the surface file or surface entities.
here is a small section as example right now it's just guesswork, some of these have taken a week to connect all the sections.
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.

View 1 Replies View RelatedI am updating my CUI ribbon for some of my customized buttons. I have changed some of the bitmap images that I have saved in my network folder for the network AutoCAD customization. However, I cannot get the Ribbon to update to show the new button images.
I have opened the CUI, browsed down to the partial CUI for our corporate configuration, then to the "Ribbon", then to the "Tabs", then to the individual section of the tab and clicked on it. Then I click on the specific button in the "Panel Preview" pane to get the properties for that button to show. Then at the bottom of the "Properties" panel, I click on the "Small Image" line to see the three dots that allow you to browse to where the .bmp is stored. I have not renamed the bitmaps, but just modified their color and the way they look. So I have to change the .bmp file to a different location in the small image properties, then change it back to the correct image name. It will update the appearance in the "Panel Preview", but will not update the actual ribbon. I click on "Apply" and "OK", and it still doesn't update the actual ribbon. I have tried closing and restarting AutoCAD after that. As a last resort, I rebooted to see if that would complete the change, but in vain.
I made sure that the network location for the bitmap files is listed in my Options > Support File Search Path (very near the top of the support file list), but that still isn't solving the problem.
How to get AutoCAD to completely forget the old image that is showing on the ribbon and repopulate it with the updated bitmap image?
We have this need to have all of the solids in a drawing to be placed in the "solid" layer.
Sometimes folks are drafting lines to develop these solids, and keeping the lines on the "solid" layer, rather than moving them to another layer, or deleting them altogether.
I could get folks to run this command before leaving the drawing.
I'm thinking something along the lines of:
Select all entities that are on the solids layer that are not solids.
If nil, great, do nothing.
If entities are selected, let me do something with them.
I'm hoping the following can be modified ever so slightly.
(setq non_solid (ssget "X" (list (cons 0 "3DSOLID")(cons 8 "solid"))))
This probably isn't the correct discussion group but not sure where else to post this.
My sales department wants to be able to create drawings based on entries in selected in their Excel qouting tool. Basically, they want to configure a product in the field, and be able to show the customer the drawing with TrueView. (They don't have AutoCAD installed).
I would think the best I can do, is manipulate a .dxf file based on their selections but that may get very complicated.
How to write some code which could create variable names like var1, var2, var3, etc. I need to do this because I have a large number to create and the actual number is variable and unknown.
Instead of manually writing a large number of line like

(setq var2 value2) etc
I used to be able to put 1 line in a loop to create and assign a large number of variables. I remember that it involved the use of the set (not setq) and read functions.

i'm newbie in customizing tools in autocad especially in creating hatch pattern. i understand that to create new hatch pattern is by adding a new hatch pattern in acad.pat file with specific angle.

I've been fighting with building a formula in a block utilizing a field from another block. I have a support steel member that once placed, will be lengthened. I need a distance from center of the pipe to the top of concrete. I created a block with a field referencing the insertion point (center of pipe) it works fine giving me this elevation. I also have another block that is the datum node. I have several fields in this block, and it is located at the bottom of the support steel plate. I am trying to create a field that takes the center of pipe elevation and subtracts the datum node elevation to get a distance. I created the formula referencing the COP elevation field and the elevation of the datum node. The information shows properly where I am building the formula, when I click evaluate, the Preview gives me ##### and when I create the datum node block that is also the output I get. I can't figure out why it won't give me the difference between the two elevation fields. I don't know what I can do differently to have that information in the datum node.
View 1 Replies View RelatedI have some code that starts a new drawing with a specific template from a lisp routine
(defun ghd:load_newdwg (template / ae-acad-object newdwg)

(setq newdwg (vla-add (vla-get-documents ae-acad-object) template))

The template location and file is stored in variable clienttemplate (and is not the standard template path set under options). All works okay except if I close the new drawing, when I return to the previous drawing that was current when the new drawing was created (i.e. the drawing that the routine was run from). I get the following error:
Command: ; error: Exception occurred: 0xC0000005 (Access Violation)
; error: Unknown exception occurred
; warning: unwind skipped on unknown exception
I assume this has something to do with the original routine not closing/finishing before switching to the new drawing. This is the last line of the routine:
(cond ((= startnewdwg 1) (ghd:load_newdwg clienttemplate)))
