Convert Block Reference into 3D Solid
Before converting this polyface mesh into a solid (this can be a hard way) I'd suggest to model it from scratch as shown in the attachment.

Hi,
Usually you can just explode a block of a solid model and all is well but your drawing was created in some other program. If I explode I get polyface mesh objects and thousands of lines.
I simply traced a polyline around the bottom flat portion of the object, ignoring the "bull nose", from start of the arc to other end. I closed the polyline across the arc.
I created a 3 point circle to develop the arc but I noticed that the round profile does not match your model by zooming in and comparing the arc to the block object.
Instead of arc I created a flat spline around the arc using all of the bottom endpoints at the "bull nose" transition. I then copied the spline and frame, trimmed the frame, and joined the entire profile to get the matching flat for your object.
I extruded the joined profile to get a solid.
I then copied the solid and extracted edges to get just the bottom front profile and I swept a bull nose profile along that path, creating a solid.
I copied the bull nose solid to the flat solid and union the two as one solid object.
Now the object can be exported as a proper watertight stl model.
BTW, I tried to explode the block and just export to stl but it fails.
Hope this helps,
Blaine

After exploding the blockreference you get a Polyface Mesh.
Depending on you ACAD version (in ACAD Rel. 14, the current format of your drawing, this is not yet possible) this Polyface Mesh mesh can be converted into a solid with the following steps:
(- Explode the blockreference, you get Polyface Meshes)
- Explode the Polyface Meshes, you get 3DFaces
- Convert the 3DFaces to Surfaces (CONVTOSURFACE)
- Create the 3DSolid (SURFSCULPT)
You get an identical "clone" of your block reference as 3DSolid.

Attached a similar, but slightly different way to get the result.
(The creation of the spline was shortened a bit (clipped) in the video)
