Does anyone know how to add new text blocks in Skill without calling a script? I am running an interactive command so calling a script is not an option.axlSetParam doesn't allow me to add a text block although I can alter existing text block parameters this way (despite the documentation).
Don't know if you can do it directly with Skill. But perhaps you can have your Skill function fprintf the script you need, execute the script using an axlShell call and then get rid of the script file.
I'm looking for this function too~~~
Thanks, That's what I do. However it doesn't work within an interactive function and I can't use "general" because I get too many crashes. I may have to revert to creating text by drawing lines. Ugly!
I don't know if this will work in an interactive command but you might want to try,
Of course all of this needs to be done using scripts...Another way could be to use a script to change the text block and put a command to restart your interactive procedure. (The trick is finding a way to save your data from one instance of the command to the other using attachments)
yes, we can add new textblock by inporting scaled plot file. But the max textblock number is 64. And, if you modify an existed textblock, you will destroy this kind textblock's text.
Programatically adding text blocks looks simple but actually is a
slightly convoluted process. You only need one function but you need five arguments
;The text you want to write
;Where you want to write the text
OrientationStructure ;Formatting for the text block
;The layer where the block is written
;Attach the text to an object
The slightly convoluted part is the OrientationStructure. You have to
know about the super secret (make_axlTextOrientation...) function for
the required structure.
;see your text block definitions
;degrees of rotation
;mirror left-right (i.e. for bottom layer)
You can get real fancy with this sort of thing. For example, I've got
code for working with symbols, namely making them presentable (PDF) for
client approval. It writes the part name, the IPC footprint name,
the number of padstacks used, the number of pins on the device,
copyright statement and occasionally dirty jokes into the part drawings
The symbol validition programs will (eventually) be added to the DesignTools project as soon as I find the time.
Have you ever reread one of your own answers, only to realize you answered the WRONG question?
I'm such an idiot. My appologies for the previous post.
textBlocks are C-structs (a.k.a "user defined objects"), are read only
by default and in general, there is no public SKILL interface for
There is a way around the problems and you can create textBlock objects
programatically in SKILL but the way to do it is highly convoluted.
Dave said, "I am running an interactive command so calling a script is not an option."
Actually, it is an option. The way this is done is you write a script
file, execute the script file in the background in another instance of
allegro, and then reload the database in your current instance.
The script file does the work you want (adding a textblock), saves the
database and exits. A second instance of Allegro is launched in
-nographic mode along with the script through the
(axlRunBatchDBProgram...) function in your first instance, so you never
see the second instance. When the second instance is finished, the
first instance of Allegro reloads the database and continues execution
of your SKILL program.
The only problem with this approach is that for that short time while
the second instance of Allegro runs in the background, you have two
licenses checked out.
The attached code adds a single textBlock to your database. Also, this
same method is useful for deleting all those unwanted layers from parts
(*.dra) when they've been dumped from a board.
