Make a command with parameter

Anonymous — Fri, 23 Jun 2017 00:06:15 GMT

Dear All,

I want transmit a outside parameter to CAD, my thinking is like following :

//outside code

class xxxxx

{

//outside code

string parameter="ParameterToTransmit";

document acdoc.SendCommand("MyCommand ",ParameterToTransmit😞

}

//CAD command

[CommandMethod("MyCommand ")]
public static void MyCommand (ParameterToTransmit)
{

}

But i don't know how to make a command with parameter .

Is it possible to create a command with parameter ?

Or is it have other solution?

Maybe you can use a macro?

Hi,

You cannot define a command with a parameter (the method attributed with the CommandMethod attribute must return void).

You can create a command with an user prompt and call the command passing ot the input.

        [CommandMethod("MyCommand")]
        public void MyCommand()
        {
            var doc = Application.DocumentManager.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;

            var promptResult = ed.GetString("\nEnter the parameter: ");
            if (promptResult.Status != PromptStatus.OK)
                return;

            // Do what you want with the parameter
        }

Then, you can hard code the call to the command with your parameter:

Using AcAdDocument.SendCommand (COM API)

acdoc.SendCommand("MyCommand " + parameter + "\n");

Using Document.SendstringToExecute (.NET API)

doc.SendStringToExecute("MyCommand " + parameter + "\n", false, false, false);

Using Editor.Command()

ed.Command("MyCommand", parameter);

hi, gile

I'm trying to load some scripts into cad to draw some lines.

Autocad 2018 .NET framework 4.6.1 C#

I've tried to use (with FILEDIA set to 0)

[CommandMethod("BATCHSCR")] public void BATCHSCR() { Document acDoc = Application.DocumentManager.MdiActiveDocument; Editor ed = acDoc.Editor; ed.Command(".script","D:\\123.scr\n "); ed.Command(".script","D:\\234.scr\n "); }

only commands in the second script has been executed.

and

[CommandMethod("BATCHSCR")] public void BATCHSCR() { string path1 = @"D:\123.scr"; string path2 = @"D:\234.scr"; acDoc.SendStringToExecute(".script " + path1 + "\n", false, false, false); acDoc.SendStringToExecute(".script " + path2 + "\n", false, false, false); }

only commands in the first script has been executed.

Is it possible to load scripts in one customize command ?

Or is it have other solution?

Using .NET to launch an AutoCAD script is like chasing mosquitoes with a bazooka.
That said, with the Editor.Command() method, you don't have to add a validation after the script file name.

ed.Command(".script", "D:\123.scr");

You can test arguments of Editor.Command() method more simply by using LISP command function directly from AutoCAD:

(command ".script" "D:\123.scr")

Using .NET to launch an AutoCAD script is like chasing mosquitoes with a bazooka.
It's a funny anology.

The scenerio is Program A outputs one script file which contains commands of drawing points and lines for each project.

Script files are placed in different subfolders named with project name.

And I wanna write a plugin to traverse the main folder to load all the script files into one dwg file.

There is no need of '\n' in parameter when using ed.Command().

ed.Command(".script", "D:\\123.scr");

It works well without "\n".

There is another problem, when using the following codes, the second line will not be executed.

ed.Command(".script", "D:\\123.scr"); ed.Command(".zoom", "e");

And there is even no history command (ZOOM E) in autocad command window.

The last command in command window is the last line of script file.

Does your script file properly ends? IOW is there a validation (space or carriage return) after the (setvar "osmode" old-osmode) LISP expression.

Uploading scr file is not supported, file extension change to txt.

This is a new line after the (setvar "osmode" old-osmode).

This file seems using LF(Unix) as the line break.

It looks like running a script from .NET is equivalent to call SendStringToExecute passing it the whole .scr file content as argument. This is probalby why it runs asynchronously.

You can try this way;

var doc = Application.DocumentManager.MdiActiveDocument; string command = File.ReadAllText("D:\\123.scr"); command += File.ReadAllText("D:\\234.scr"); command += "_zoom\n_Extents\n"; doc.SendStringToExecute(command, false, false, true);

Graceful solution!

It works perfect. Thank u so much.

During the progress, unit setting window will prompt twice. Solved by adding "-" between "_" and "UNITS".

Reference:

AutoCAD help files.

A script can execute any command at the Command prompt except a command that displays a dialog box. In most cases, a command that displays a dialog box has an alternative version of the command that displays Command prompts instead of a dialog box. Most alternative versions of a command start with a hypen (-). For example, use -INSERT instead of INSERT.
