AutoCAD Visual LISP / AutoLISP :: Check If Layer Is In One Of Multiple Lists
Jul 18, 2013
I am trying to write a piece of a program that gets the layers from a drawing, and checks each one against a list of layers. If the layer is not a member of any of the lists it asks the user which layer list to add it to. This is what I have so far, but every time I try to run it I get a bad argument error.
Depending on the user's choice the layer gets written to an external file where the layer lists get their layers from in the beginning and then adds the layer to the relevant list to use later in the program.
I am writing a program to grab a bunch of layers from a list, check a drawing to see if the layers are on the list, and if not save to an external file. I have the second part of the program done, but I can't get the first part to work.
I am trying to open a file read the contents and save it to a list.
Here is the code I have so far, but it doesn't even get into the foreach statement.
Someday the light bulb is going off and I will understand mapcar and lambda. However.....I have a program that reads an excel file sheets. Sometimes the sheet only has 1 column, sometimes 2 or more.
I need to convert the saved values from the sheet to a list with the text spaced evenly. Unfortunately the text lengths vary. I would like a subroutine to pass the list to and return a list of strings with text aligned with padded spaces allowing for the longest text in each column. I am using the new list in a dialog box with fixed_width_font=true (so columns align).
I'm creating a drawing set that has over 100 sheets with varying amounts of viewports on each sheet (from one to four). Each sheet is its own file, so there is only one layout per file. For each section of the drawing set, the viewports will have the same layer state.
Is there were a way to update the layerstate of each viewport through a batch LISP routine? This would save me DAYS in opening each file, importing the layer state, and restoring it for each viewport. It seems straight forward, but I have no idea where to start with batch routines.
I often work on drawings which have multiple xrefs, each having up to 100 Layers or more, so the layer manager can be a bit difficult to trawl through to find a local layer to select.
I know how to create a local layer filter using the code ~*|* from the new filter area in layer manager.
Ideally all I want to have to type in is: LOCAL and then the local layer filter would be created, with the filter name being Local-Layers (or similar).
We have developed processes, standard operating procedures, work instructions (whatever you want to call it) for several tasks we do on a regular basis. More importantly, tasks that we don't do on a regular basis. On some processes, performing certain commands is a critical step in the quality of the product. I have also developed a lot of lisps to streamline these processes. Of course there are commands that just don't make sense to try and include into existing lisps.
The problem we're having though, is that people are not following the processes. I don't know if they think they are smarter than the process, or if they don't understand the process, or if they are just complacent.
One of the things that would really work to get everyone to follow the process, is to have my lisp routines check to see what the last entry at the command line was.
For example, if one of my lisps depended on the drawing be saved, well, instead of putting the save command in the lisp, sometimes it would be beneficial to check to see if the drawing was saved in the first place. Kudos to those who do follow the process, they do save the drawing, and then run the lisp. On rather large files, I would prefer not to save the drawing twice, back to back.
There are a lot more benefits to checking to see what the last user entry was, in a certain drawing.
I want autolisp program to check overlap like in closed or open polyline with any other entity in the drawing, whether other entity is overlapping inside the polyline or not, i am beginner in autolisp and want to know exactly which functions are used or the program itself Also if possible to check circular overlap of one polyline with itself.
I've been working on a lisp to set up basic settings such as text styles, dim styles, discipline specific layers and things of that nature.
I have a prompt to ask for a discipline designator as a string. I want to have an If statement or a conditional to read that string and check for a "C" if it finds it I want to have it set up a dimstyle to decimal feet ect and if not do it as architectural units.
This is just a test lisp that I'd like to add to the main one listed above...
How do I check, with LISP, if a System Variable is read only? In particular ANNOTATIVEDWG. This one is read/write when there are no annotative objects in a drawing, but read-only if there are.
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 would like to create a lisp program that check the attributes of block using an external database, if tag1+tag2+tag3 = XXYYYYYYZZZZZZZZ ok end program, if not make a circle on block :
How can I iterate through and check the object type of all objects in model space? And... then delete them if they are certain types... like lines, circles, polylines, text, mtext, etc?
Technique that can check the current plotter name for the current tab and assign it to a variable? i.e. can it be assigned to a variable to check if if equals "myplotter1". The next step - is there a technique to change the plotter name to "myplotter2.pc3".
I have partially done the latter part of this in the past using the -plot command line to ASSIGN a new plotter but I would really like to only run the routine if it really needs to.
lisp..It work fine but just that i need some minor modificatio to it...At moment, when i activate the lisp, it will automatic select all dimension,leader and multileader to a layer call "DIMENSION"...Anyway i wonder if it is possible to prevent any dimension,leader or multileader in layer "Section" will not be change to layer "Dimension"?
Say I have 2 items, one is on layer "M-Duct" and the other on "M-Pipe" (they are in the same drawing). Any lisp routine that would create the layers "M-Duct-New" and "M-Pipe-New" (based on the same color and LT as the original layers) and then move those objects to the newly created layers?
Possible to link an xref layer and local layer so they display the same (eg. sync viewport colour, linewieght, line type)?
I insert xref's for my base drawing but legend is on local layers and I would like to be able to ensure that the line colour and linetype always match...
I have a customized button to draw an ‘ac-arrow’. I created a lisp to create the layer “G-ANNO-LEDR”
if the layer name is not found. The advanced part I would like is:
Current layer: E-ANNO-WIRE
Ac-Arrow Leader: G-ANNO-LEDR
OPTION 1:
If, say I am on current layer “E-ANNO-WIRE” and need to draw my “ac-arrow” leader, and continue working
on the original layer “E-ANN-WIRE” (and have the leader be drawn [remain] on the layer “G-ANNO-WIRE”).
With this option, I have the block “ac-arrow” imbedded in my template drawing file to have the block at hand.
With this option, the layer “G-ANNO-LEDR” will be created IF it is not on the drawing.
OPTION 2:
- Currently be on layer “E-ANNO-WIRE”
- Bring in the block “ac-arrow” from my block library “L:AutoCADSymbols”
- Draw the “ac-arrow” leader which will be on layer “G-ANNO-LEDR” (this layer created IF it is not
on the current drawing).
- After the leader is drawn’
- Be put back to the layer I was, “E-ANNO-WIRE”, and continue working.
The OPTION 2 is what I would really like to have. A while back, I happen to see one like OPTION 2, but I cannot
find it anymore on the users groups. I have been searching for a while now.
Currently, I use the button in my customized toolbar (see image) and have to have the “ac-arrow” block in my drawing and have its layer created in the drawing.
Any script that when ran will set lineweights of a layer based on what color the layer is assigned. For instance if I have 3 lines that are green on 3 different layers. I need the script to change all 3 layers lineweight to .015mm. I have drawings that are inconsistant with layer names so layer translator and methods of that nature will not work because I do not know all the layer names and I have 100 drawings to do this to.
