Create Layer and Line C#

k005 — Fri, 26 Mar 2021 15:04:36 GMT

Hello

I want to create a command that draws Line by Layer.

sample:
Layer name: Grobeton
Layer Color: 2

osnap : Intersection,MidPoint,EndPoint = will be marked

and I will draw a line that will be active with this layer ... How can I do this?

Thanks.

Hi @k005

so you want to draw a line in a specific layer? and give it a specific color ?

and you want to programmatically activate 2D Object Snaps: Intersection, MidPoint, EndPoint?

Hi @essam-salah

Yes that's right

@k005

so why you don't do it manually: set the current layer to the layer you want and OSnap you want?

what is the point?

give example please

for example :

I'll go over an existing drawing. and this will be on the layer I want. osnap, on the other hand, is just to activate object

capture for the moment. it is ok even if it is not ..

@essam-salah

I don't think screen recording is needed.

I just want to do this: create a layer that does not exist in the dwg file (give it color) and draw a line with it. so much.

osnap automatically catches the point I mentioned, better if it is activated.

@essam-salah

Even if the layer is present, it doesn't matter. let it occur again. according to the color I set

hi @k005

try this:

using aApp = Autodesk.AutoCAD.ApplicationServices;

[CommandMethod("cieCreateLayer")] public static void CreateLayer() { var doc = aApp.Application.DocumentManager.MdiActiveDocument; var db = doc.Database; var editor = doc.Editor; // ask user for layer name var promptResult = editor.GetString("Layer Name:"); if (promptResult.Status != PromptStatus.OK) { editor.WriteMessage("\nNo String Found\n"); return; } string layerName = promptResult.StringResult; // set osnap aApp.Application.SetSystemVariable("OSMODE", 32); // Intersection aApp.Application.SetSystemVariable("OSMODE", 2); // Mid Point aApp.Application.SetSystemVariable("OSMODE", 1); // End Point using (var ts = db.TransactionManager.StartTransaction()) { // get layers table var layersTable = (LayerTable)ts.GetObject(db.LayerTableId, OpenMode.ForWrite); // create layer if not exist if (layersTable.Has(layerName) == false) { var newLayer = new LayerTableRecord(); newLayer.Name = layerName; layersTable.Add(newLayer); ts.AddNewlyCreatedDBObject(newLayer, true); } // set color var layer = (LayerTableRecord)layersTable[layerName].GetObject(OpenMode.ForWrite); layer.Color = Color.FromRgb(255, 0, 0); // set current layer db.Clayer = layer.Id; // commit changes ts.Commit(); } }

@k005

just replace the osnap 3 lines with:

// set osnap aApp.Application.SetSystemVariable("OSMODE", 32 | 2 | 1); // Intersection, Mid Point, End Point

just discovered Autodesk.AutoCAD.EditorInput.ObjectSnapMasks is a flags

Hi @essam-salah

so far...

only the command will not exit and the LINE command will run.

And it shouldn't ask for the layer name. It should be fixed.

So we will enter the layer names in C # code
