Hi SS,
We also have the need to transfer our labels from CAD to SkyJUMP.
1) Use Michael's DXF plugin to import the (simple) DXF. It comes in with a
Text attribute.
2) Use my "Extract Layer by Attribute" plugin, (which defaults to the
attribute "Layer") to break the dxf-derived layer back out to the original
layers.
3) Change the style on layers that have text to:
a. Enable Labeling on the "TEXT attribute"
b. Set the horizontal alignment to LEFT for layers with comment text.
c. Set the Height attribute to TEXT_HEIGHT.
d. Check Scale labels with the zoom level
If you follow these steps, you should get reasonably good text in your OJ
map from the CAD original. I recommend exporting as an R12 dxf if
possible. You can use a free program like EveryDWG to do the conversion.
regards,
Larry
