Tip for Week 12/8/03

 

So you need to to convert that really cool 3D view into just lines or polyline entities on a single plane do you?  No problem, just follow along with the following description of how to do just that!  This trick works with mixed results for turning text into editable objects also.  These methods allow users to "flatten" 3D objects and leave the existing 3D entities alone.

The first method is to use the standard WMFOUT command.  This command allows users to select entities from the current drawing and convert them into a WMF file.  The command will also retain the entities relation to the current view and retain whether or not the Hide command was issued.  Issue the WMFOUT command and after naming the new WMF file, select the entities that you need to translate into 2D polylines.  Nothing will be deleted or modified in your current drawing.

Open a new file and issue the WMFIN command.  Select the WMF file that you just created You will now be inserting a block that can be exploded into just 2D polyline entities.  If you explode the entities again, they will be simple lines.

Don't forget to use the Hide command before creating the WMF file.  All of the exploded entities will remain on the layer that the WMF file was inserted on and have the color attribute of the original layer color, not "ByLayer".  Edit your Layer properties for each item as needed. 

If you are "flattening" 3D objects, you can scale the inserted WMF block using the Reference option of the Scale command to replicate their original size.

A second method is to set up a printer for the creation of a DXB file.  Print your 3D view as a DXB file and then use the DXBIN command to insert the DXB file into AutoCAD.  The entities can only be inserted into your file as line entities and at the 0,0,0 origin.  This method is nowhere near as good as the WMF trick, but has some advantages depending on your use.
