Viewer demo problem

[AndyStephenson]

Hi,

I have installed the component into D2005, and when I run the viewer
demo, load a dxf, and hit the layer button, the program throws an exception.

Is this a known problem? If so, what's the fix.

Also, I have noted from the demos that there appears to be very little
in the way of adding entities at run time using the mouse. Are there any examples of this?

Are there any examples that show the use of the Layer for the entity -
how to select or create a new layer?

Is there a redlining demo to look at?

Please advise.

...Andy

It is necessary to find procedure <b>lvLayersDeletion</b> in the unit <b>fLayers</b> and to replace it like the following:

Code: Select all

<b>unit</b> fLayers;
...
<b>procedure</b> TfmLayers.lvLayersDeletion(Sender: TObject; Item: TListItem);
<b>begin
  if not</b> (fsModal <b>in</b> FormState) <b>then</b>
    Dispose(Item.Data);
<b>end</b>;

The following demos have additing examples:
<ul><li><b>Add new entities</b></li>
<li><b>Editor</b> (includes selecting entities by mouse and displayes the layer)</li>
<li><b>TextChange+Color2LineWeight</b> (include example of creating <b>TsgDXFImage</b>)</li></ul>
These demos will be improved in the next version of CADImportVCL. The release is awaited at the beginning of December, 2006.

Unfortunately we have no visual tool for creating layers. We plan to add it in future versions of the library.

Next version of CADImportVCL will not include Redline. Please contact us on info@cadsofttools.com to get more info on this question.
