copy layer from DXF to DXF

[corentin]

Hello, Sergey!

I would like to be able to import a second DXF and copy one layer, and paste this layer( with the entities) on my first DXF all entities.
I have try a lot of exemple in this forum, but i have not find any solution.

have you an exemple for me please?.

Hello,

Please try the following code:

Code: Select all

	CADLayer lay1 = new CADLayer();
	lay1.Name = "MyLayer";
	lay1.Color = Color.RoyalBlue;
	lay1.Visibility = true;
	this.cadImage.Converter.Layers.Add(lay1);
	this.cadImage.Converter.OnCreate(lay1);
	this.cadImage.Converter.Loads(lay1);

thanks you, it works perfectly.

but i use the viewer form and when in click to show the layer form, my new layer, isn't in the list although my polyline is on the screen! have you an idea?

It is necessary to use private void AddRecordToLayerList(string name, Color color, bool visible, bool freeze) available in the demo.

In general copying entities of some layer from one file to another could be implemented "manually". Please check a code below:

Code: Select all

private void AddEnt(CADConverter Conv, CADEntity ent)
{
	Conv.Entities.Add(ent);
	Conv.OnCreate(ent);
	Conv.Loads(ent);	
}

private void button2_Click(object sender, System.EventArgs e)
{
	if(cadImage == null) 
		return;
	cadImage.Converter.PointDisplayMode = 0;			
	cadImage.UseDoubleBuffering = false;

	CADLayer entExtLayer = new CADLayer();
	entExtLayer.Name = "Extended Layer";
	entExtLayer.Color = Color.RoyalBlue;
	entExtLayer.Visibility = true;
	this.cadImage.Converter.Layers.Add(entExtLayer);
	this.cadImage.Converter.OnCreate(entExtLayer);
	this.cadImage.Converter.Loads(entExtLayer);
	this.AddRecordToLayerList(entExtLayer.Name, entExtLayer.Color, true, false);
			
	CADImage xRefcadImage = new CADImage();
	xRefcadImage = CADImage.CreateImageByExtension(@"d:\LinesInTheBlock.dxf");
	xRefcadImage.LoadFromFile(@"c:\LayerToBeCopied.dxf");

	for (int i=0; i<xRefcadImage.Converter.GetCounts(CADImport.FaceModule.ConvSection.Entities);i++)
	{
		CADEntity ent = xRefcadImage.Converter.GetSection(CADImport.FaceModule.ConvSection.Entities).Entities[i];
		if (ent.Layer.Name == "0")
		{
			switch(ent.EntType)
			{
				case CADImport.EntityType.Point:							
					CADPoint tmpPoint = ent as CADPoint;
					CADPoint entPoint = new CADPoint();
					entPoint.Point = tmpPoint.Point;
					entPoint.Point1 = tmpPoint.Point1;							
					entPoint.Color = tmpPoint.Color;
					this.AddEnt(this.cadImage.Converter, entPoint);
					break;
				case CADImport.EntityType.Line:											
					CADLine tmpLine = ent as CADLine;
					CADLine entLine = new CADLine();
					entLine.Point = tmpLine.Point;
					entLine.Point1 = tmpLine.Point1;							
					entLine.Color = tmpLine.Color;
					this.AddEnt(this.cadImage.Converter,entLine);
					break;
				case CADImport.EntityType.Circle:								
					CADCircle tmpCircle = ent as CADCircle;
					CADCircle entCircle = new CADCircle();
					entCircle.Point = tmpCircle.Point;
					entCircle.Radius = tmpCircle.Radius;							
					entCircle.Color = tmpCircle.Color;
					this.AddEnt(this.cadImage.Converter,entCircle);
					break;
				default:
					break;
			}
		}				
	}
	this.cadImage.GetExtents();
	this.cadPictBox.Invalidate();			
}

thank you , for your reply.

i have an other question,
With the viewer i can't use any event ,like "mouseclick"etc... how can i do , for use it??

thank.

Hello,

Viewer demo contains:
private void cadPictBox_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
private void cadPictBox_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

where mouse button clicks are processed.

Sergey.

Thank you, for your help.


I have found un Bug with the "CADViewerControl" class.
I use the GetRealPoint(x,y) method to determinate where i click, but when the scale is more than 100%, coordinates in the "StatusBarPanel" is wrong, i can't explain this.

i have the same trouble with this code:

Code: Select all

int x =viewer->CurrentXClickPosition;
int y =viewer->CurrentXClickPosition;
CADImport::DPoint point = viewer->GetRealPoint(x,y);

before 100% the origine of my DXF file is on the left bottom, and after 100% this origine move to the center of the plan.

i enclose screenshots.








i have a two other question:
is it possible , in the "CADViewerControl", to disable the zoom by box selection (left click)??

in order to buy Cadimport.NET , what is the difference between programmatic entities creating and programmatic editing??

thanks

We have doubtes that there is a bug. CurrentXClickPosition shouldn't be used for such purposes. It surves for determining drawing's offset among inner cadPicture space. Could you please send us to support@cadsofttools.com your file and the whole demo to test the problem?

Such functionality is unavailable.

There is no difference between programmatic entities creating and programmatic editing. The difference is between Standard and Professional versions. Editor demo contains visual means of adding and editing entities with Professional version. Trial version works like Professional.

Hello Sergey!

I have bought a professional licence.

I always have the same trouble with coordinates, i will send you an example.


i have register my licence:

Code: Select all

ArrayList^ regDat = gcnew ArrayList();
			regDat->Add("xxxxxx");
			regDat->Add("xxxxxxx");
			String^ Key = "xxxxxxxx";
			Protection::Register(Key, regDat, false);
			viewer->Invalidate();

I have a second trouble, I want to save my dfx file with :

Code: Select all

MyCADviewerControl->SaveAsDXF();

i enter a name to my file , but i have not any file on my save repertory.

Hello Corentin,

I always have the same trouble with coordinates, i will send you an example.

i have register my licence:

Code: Select all

ArrayList^ regDat = gcnew ArrayList();
			regDat->Add("xxxxxx");
			regDat->Add("xxxxxxx");
			String^ Key = "xxxxxxxx";
			Protection::Register(Key, regDat, false);
			viewer->Invalidate();

Do you have a problem with coordinates or with the registration process?

I have a second trouble, I want to save my dfx file with :

Code: Select all

MyCADviewerControl->SaveAsDXF();

i enter a name to my file , but i have not any file on my save repertory.

We tested the following code on a ViewerControlDemo from the CAD Import .NET package:

Code: Select all

this.cadViewerControl1.SaveAsDXF(@"c:\test.dxf");

It works.

hello Sergey.

today i have two troubles:
1) save my new DXF.
2) coordinates in the plan.

For save my plan , i have test your code:

Code: Select all

    this.cadViewerControl1.SaveAsDXF(@"c:\test.dxf");

but unfortunately save don't works. the file isn't create. have you an idea?

For coodinates in the plan i will send you a example.

hello sergey,

can you explain to me , how can i delete a layer (with the entities) in a DXF file , when i use the cad viewer in the library cadimport.net ???

thanks you

Hello,

Here goes a code example how to delete a layer with entities:

Code: Select all

       private void mmiDeleteLayer_Click(object sender, EventArgs e)
        {
            if (this.cadImage == null)
                return;
            this.cadImage.UseDoubleBuffering = false;

            for (int i = this.cadImage.Converter.GetCounts(ConvSection.Entities)-1; i>=0; i--)
            {
                CADEntity ent = (CADEntity)this.cadImage.Converter.GetSection(ConvSection.Entities).Entities[i];
                if (ent.Layer.Name == "LayerToBeDeleted")
                    this.cadImage.Converter.Entities.Remove(i);
            }

            CADGroup layersSection = this.cadImage.Converter.GetSection(ConvSection.Layers);
            
            for (int i = layersSection.Entities.Count - 1; i >=0 ; i--)
            {                
                CADLayer entLayer = (CADLayer)layersSection.Entities[i];
                if (entLayer.Name == "LayerToBeDeleted")
                    layersSection.Entities.Remove(i);
            }
            this.DoResize();
        }
