hello,i am new in programming and in my first succesfull attempt i developed a windows form based stand alone application in Vb.net 2010 that calculates all the geometry data needed for a Spur Gear ,my final goal is to send all Calculated data needed in Autocad 2012 and draw automatticly the Spur Gear.
At first i started to experiment my self with a simple only task (created a new project only for this) to draw 4 circles with the same center (radius1,2,3,4) in autocad with a simple click of the command button.
The code i used is the following (for 1circle) but it returned a error like this>> SendACommandToAutoCAD()-->>Could not load file or assembly 'Acmgd, Version=18.104.22.168, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Public Sub SendACommandToAutoCAD()
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
'' Draws a circle and zooms to the extents or
'' limits of the drawing
acDoc.SendStringToExecute("._circle 2,2,0 4 ", True, False, False)
acDoc.SendStringToExecute("._zoom _all ", True, False, False)
The AutoCAD .NET API Assemblies (acadmgd.dll, acmgd.dll...) CANNOT be used in stand-alone exe app. They can ONLY be used inside AutoCAD (NETLOADed DLLs into AutoCAD).
In your case, if you must use a stand-alone app, then you can use Acad COM API to automate AutoCAD. But do not addict to use something like "SendCommand()". Explore Acad COM object model to create/manipulate AutoCAD entities and Acad environment.
However, you need to be carefully analyse the app's usability to deside if you want to automate Acad from an external exe or not.
OTH, if user mainly collects data via your app, and mostly make Acad draw something later, then your app can store the entered data somewhere (file, database) and you have code in AutoCAD that reads data in and does the drawing, thus, avoid the out-process AutoCAD automation.
thanks for the reply,much appreciated and helpful,now i understand the type of the error,maybe i try another aproach to my problem.
If you want to create a DWG directly from your executable, you could licnese RealDWG - www.autodesk.com/realdwg.
