DXF Import&Layer select

[Willi]

Hello,

I want to import an DXF-drawing, change the layers and print the whole drawing automatically by VB.net.
Now I don't know how to use the layer selection procedure in VB.NET (and the import procedure). I think I don't need to view the drawing.

Can someone help me with some code in VB.net?
I think, the easiest way would be to use the "CAD Import .NET for Compact Framework" or the "CAD Import.NET".

Any suggestions are welcome.

Hello Willi,

There are two ways to switch off or on a necessary layer:

<ul><li>Basing on the <b>Viewer</b> demo (please find it in the ..\cadimportnet\sources\Viewer\VB\.. folder of the package):

use the following method:

Code: Select all

FCADImage.SetLayerVisible(Index, val)
<i>Index</i>
  An index of the layer in the collection of layers. 
<i>val</i> 
  A value which the specified layer's visibility will be set to. 

</li>
<li>Basing on the <b>Import</b> demo (please find it in the ..\cadimportnet\sources\Import\VB\.. folder):

Code: Select all

CADLayer L1= FCADImage.Converter. LayerByName("Layer1")
L1.Visible = <font color="blue">false</font id="blue">

Public Function FCADImage.Converter.LayerByName(<font color="blue">ByVal</font id="blue"> AName <font color="blue">As String</font id="blue">)  <font color="blue">As</font id="blue"> CADLayer
<b>Parameters</b>
<i>AName </i>
  A name of the layer to return.</li></ul>

For getting a list of layers' names use the following methiod:

Code: Select all

Public Sub FCADImage.Converter.GetLayerNames(<font color="blue">ByVal</font id="blue"> S <font color="blue">As</font id="blue"> ArrayList, <font color="blue">ByVal</font id="blue"> DoClear <font color="blue">As Boolean</font id="blue">, <font color="blue">ByVal</font id="blue"> IncludeUnused <font color="blue">As Boolean</font id="blue">)
<i>S </i>
  An ArrayList where the layers' names will be added. 
<i>DoClear</i> 
  A value indicating whether to clear the specified ArrayList before adding the layers' names to it. 
<i>IncludeUnused</i> 
  A value indicating whether to include the names of layers that don't contain any entities.
