Hi everyone. When I import this .dwg file as a 2D sketch it has to many unnecessary lines. 
When I import it as a 3D sketch it looks good, but recognize all the entities as 2620 imported curves. It doesnt seem usable too.
Please help me to import these drawings as a normal 2D sketches. The original file is attached. Thanks.
You need to clean up the DWG or select what you import:
The extra lines are how they shade/hatch the profiles.
As Frederick Law has noted, these are fill/hatches which were converted to polyfaces/lines ... you can delete them manually or open them in a dwg program (draftsight or acad) .. (image file w/delete polylines in Rhino3D)
Thank you!
Hello,
To further what Mr. Law and Mr. Salvador have posted, the hatches are composed of multiple instances of a "solid" entity in DraftSight:
Drag a box selection around the multiple views to select all entities in the views:
In the selection filter drop down, select "Solid" (The number is their quantity in the selection):
Click Smart Select:
and set these options and click OK:
Press the Delete key.
Repeat the above and select Hatch for the Entity type as there are also hatches.
Delete whatever else is not needed.

..yes!.. and/or, select "Solid" entities and assign them to the "Hatch" layer and turn the Hatch layer off or delete them.

LOL!.... sadly, I have >10yrs of that layer stuff in my head. Although, I have to admit layers have merit. (damn the acad world!)
"layer" is just another category to organize data.
Put each "layer" in another "sketch" or "part".
Brilliant! Thank you!
