Adding TsgCADMLine ?

[bilcan]

Hi,

I'd like to add a MultiLine (for example Double) entity to CAD Image but I couldn't find a demo or explanation, could you give me an simple example

Hello Bilal.
Here is the snippet that shows MultiLine creation. The number of lines in MultiLine defined by TsgMLineStyle.Entries. TsgMVertex.Point and TsgMVertex.Direction define MLINE geometry. Please note, MultiLine can't be exported to DXF with VCL export component current version.

Code: Select all

  style := TsgMLineStyle.Create();
  style.Name := 'my_style';

  M := TsgMLineEntry.Create;
  M.Offset := 5;
  M.Color := clBlue;
  style.AddEntity(M);

  M := TsgMLineEntry.Create;
  M.Offset := 15;
  M.Color := clRed;
  style.AddEntity(M);

  Img.Converter.Loads(style);
  Img.Converter.OnCreate(style);
  Img.Converter.Sections[csMLineStyles].AddEntity(style);

  mline := TsgCADMLine.Create();
  mline.Scale := MakeFPoint(1, 1, 1);
  mline.Style := style;
  mline.Flags := 1;
  mline.Justify := 0;

  mvert := TsgMVertex.Create();
  mvert.Point := MakeFPoint(500, 0, 0);
  mvert.Direction := MakeFPoint(100, 100, 0);
  mvert.Miter := MakeFPoint(0.0, 20.0, 0.0);
  mvert.NewList();
  mvert.NewList();
  mvert.NewList();
  mvert.Params[0, 0] := 0.0;
  mvert.Params[0, 1] := 1.0;
  mvert.Params[1, 0] := 1.0;
  mvert.Params[1, 1] := 1.0;
  mline.AddEntity(mvert);

  mvert := TsgMVertex.Create();
  mvert.Point := MakeFPoint(0, 500, 0);
  mvert.Direction := MakeFPoint(100, 100, 0);
  mvert.Miter := MakeFPoint(0.0, 20.0, 0.0);
  mvert.NewList();
  mvert.NewList();
  mvert.NewList();
  mvert.Params[0, 0] := 0.0;
  mvert.Params[0, 1] := 1.0;
  mvert.Params[1, 0] := 1.0;
  mvert.Params[1, 1] := 1.0;
  mline.AddEntity(mvert);

  mvert := TsgMVertex.Create();
  mvert.Point := MakeFPoint(-300, 100, 0);
  mvert.Direction := MakeFPoint(100, 200, 0);
  mvert.Miter := MakeFPoint(0.0, 20.0, 0.0);
  mvert.NewList();
  mvert.NewList();
  mvert.NewList();
  mvert.Params[0, 0] := 0.0;
  mvert.Params[0, 1] := 1.0;
  mvert.Params[1, 0] := 1.0;
  mvert.Params[1, 1] := 1.0;
  mline.AddEntity(mvert);

  Img.Converter.Loads(mline);
  Img.Converter.OnCreate(mline);
  Img.CurrentLayout.AddEntity(mline);

  Img.GetExtents();
