DWG issue - Randomly won't form some faces
-
Whenever I import a flat DWG, it always seems to struggle to form faces on completely flat geometry.
Or sometimes, a face will form, but in the process, it will remove all other ungrouped faces on the same plane.
For houses, as a workaround, I leave the DWG grouped and closed, and then redraw every line in another group, usually with the rectangle tool.
With gardens and areas with almost freehand drawn curves, this becomes a big issue and is extremely time consuming.
What can I use as a workaround? Even copying a pasting lines from the DWG to a separate, larger face won't form closed geometry!
This happens with 2D DWG's that were drawn on a completely flat plane in Vectorworks/AutoCAD and then imported into sketchup.
Is there any plugins to do something to the geometry so it works as it should? I've had this issue/bug since Sketchup Pro 8!

A common reason for missing faces with imported DWG files is gaps at endpoints. Gaps in the imported DWG do not a SketchUp bug make. There are a few different plugins that can find and close gaps. One is Close Opens from Smustard.com.
Tracing the imported lines is one way to create the faces. Another would be to draw a rectangle overlaying the edges (explode the group/component) and then select all and run Intersect Faces. You'll be able to find the gaps by noting which regions don't get separated into different faces.

Thanks for the reply. Unfortunately, even if I select a rectangle larger than the whole of the imported DWG and intersect faces, it says "no intersections found" when there should be a lot of them!
Even drawing rectangles with the sketchup tool (over a rectangle in the DWG), it won't form a face, only the linework. If I leave the DWG in a closed group and trace the rectangle, a face will correctly be drawn on top, it just won't work when editing the DWG linework. Essentially, the imported lines don't really work with sketchup!
This has been an issue in Sketchup 8 Pro, 14 and 16 (the 3 versions I've used to date).

Can you share an SKP file in which this occurs?
