autocad

问题 For last two days I have looking for sample code with steps which may help me to understand the Autocad API. so I can use the code in C#. [CommandMethod("LISTGEn")] public static void ListEntities() { Document acDoc = Autodesk.AutoCAD.ApplicationServices.Core.Application.DocumentManager.MdiActiveDocument; Database acCurDb = acDoc.Database; using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction()) { // Open the Block table record for read BlockTable acBlkTbl; acBlkTbl =

问题 I'm receiving an ArgumentException "Object type cannot be converted to target type" but it doesn't make very sense to me. the method I'm calling has the following signature: public void Scan(IProgressStatus monitor, string registryPath, string startupDir, string addinsDir, string databaseDir, string scanFolder, string[] filesToIgnore) I tried to pass monitor instead of remMonitor but the exception is still thrown. All the arguments have values except scanFolder that is null (but passing

问题 I have encountered a problem. My company bought a VB developed plug-in,which allows us to print the dwg files to a shared printer.This plug-in works fine with version 2009 and before. Instead of tapping 'plot' in command window, we tap 'eplot' ,the plug-in would then connect to the remote printer,upload,print and back up the dwg files. But after we upgraded to 2010,the problem arose. The 'eplot' command wasn't being recognized by 2010. I had heard that 2010 doesn't support VBA applications,

问题 I'm using a not-fully-exposed API in the add-on that I'm currently writing. Some classes there are still kept internal, although some public methods require parameters of these types. To handle the problem I tried to use dynamic typing with a helper DymamicObject implementation. I was pretty successful doing so but at one point I get a RuntimeBinderException, which doesn't tell me the exact details: "The best overloaded method match for Autodesk.Civil.DatabaseServices.PressurePipeNetwork

问题 I try to implement a simple copy operation between two Autocad documents via COM in Python. from pyautocad import Autocad, APoint from comtypes.client import GetBestInterface # Get acad application acad = Autocad(create_if_not_exists=True) # Create a new document doc1 = GetBestInterface(acad.Application.Documents.Add()) # add a circle in this document and make it visible circle = GetBestInterface(doc1.ModelSpace.AddCircle(APoint(0.0, 0.0), 1.0)) doc1.Application.ZoomExtents() # create another

问题 I'm trying to automate some drawing in AutoCAD using Python and I work with SelectOnScreen method. Here is a code in VBA: Dim FilterType(0) As Integer Dim FilterData(0) As Variant FilterType(0) = 0 FilterData(0) = "TEXT" selection.SelectOnScreen FilterType, FilterData In Python I use it as: FilterType = win32com.client.VARIANT(VT_ARRAY|VT_I2, [0]) FilterData = win32com.client.VARIANT(VT_ARRAY|VT_VARIANT, ['TEXT']) selection.SelectOnScreen(FilterType, FilterData) and it works in AutoCAD.

问题 I have a Triangle as a polyline and I want to draw an Altitude. I give the command "line" or "_line" the right points but AutoCAD draws the line from the vertex to the adjacent vertex. It's not just in AutoLISP, AutoCAD won't let me draw a line from a vertex to the middle of an edge in a polyline. How can I do that? I thought of adding a vertex in the polyline, but this didn't help that much. I tried to add connector: a circle or another object close enough to the line and connect the

问题 I have a user with issues loading a .Net assembly into AutoCAD. I get the following error: Cannot load assembly. Error details: System.BadImageFormatException: Could not load file or assembly (hr = 0x80131018) They are using an anit virus package called Endpoint Security and when this is turned off, the load works. I am not a .Net expert and was hoping there might be a friendlier solution than me suggesting the user put their anti virus package in the trash!? But I've no idea where to start,

问题 I was trying to load AutoCAD 2015 from .Net process so that I can send commands to the document to create/modify blocks. I tried both of these approaches but none of them seems to work. 1st approach: AcadApplication app = new AcadApplication(); app.Visible = true; 2nd approach: var t = Type.GetTypeFromProgID("AutoCAD.Application", true); dynamic obj = Activator.CreateInstance(t, true); In both of the cases I am getting COM exception. Any help? It's not a duplicate as mentioned in comments, I

问题 I am getting "Attempted to Read or write protected memory" when I try to perform some parallel operations. I am reading AutoCad Databases into to memory to do some data mining. I can do this with a regular for loop but not with a Parallel.ForEach . Any ideas? Parallel.ForEach(_Files, (currentFile) => { var _File = currentFile; using (Database _Database = new Database(false, true)) { _Database.ReadDwgFile(_File, FileOpenMode.OpenForReadAndAllShare, false, null); _Database.CloseInput(true); //
