Having problems opening a .dwg file piping drawing, make some edits and save as .dwg. When converting, the model doesn't come with the drawing. I tried several options with no luck. Right now the SolidWorks drawing is just random lines in space. Any ideas on what I may be doing wrong?
Hello,
Please add some screen shots, or better yet, upload your files, if permissible.
How can I attach a file to a forum post?
Outline the steps your took, too, please.
Less guessing.

Hello,
The construction drawing is confidential so I will not be able to attach. Below are screenshots of the import wizard and setting i had. I was unable to get the "Import to a new part" to work.
Steps taken,
- Opening .dwg file in Solidworks using Import Wizard.
Tom Gagnon is on the right track here.
You stated that the model is not being created. If I am following this correctly, you have a 2D drawing that you are attempting to import into SolidWorks, correct? The information is not in the 2D drawing for it to automatically create the model. Especially in a single ISO view. If you had the standard Front, Top and Right views you could use them to manually create a 3D view but to my knowledge even with the 3 views the software is not able to automatically create a 3D model.
Hello,
Riser diagrams will be a tough import as there's not an iso snap in SW.
How about opening the DWG in DraftSight and break the file into "chunks" for individual import.
Also, as shown in the dialog above, since there's [no] PLINE width subcommand, while in there, set all PLINE widths to zero.
Take a look around too, perhaps you'll be able to see what the "missing 16" are and cobble them so that they can be imported (somewhat).

(referring to context of Kevin's comment but addressing the OP)
From what I can tell, you are taking a 2D drawing DWG and placing it in a 2D drawing SLDDRW. As such, nothing present will carry backwards into parts or assemblies. It seems that you are intentionally creating a drawing from a drawing.
As such, why use Solidworks at all to present your document? I would simply use Draftsight (or NanoCAD or even AutoCAD LT) instead of Solidworks to handle this 2D document. Solidworks is excellent at making drawing views of parts and assemblies, but sketch-drawings in a drawing are pretty badly handled compared to object views in a drawing. You may be setting yourself up for serious problems this way unless you choose to lock it down to avoid accidental changes.
Or, you could start a new Part, recreate a 3D Sketch in the Part to represent the design in lines, then create a view from that part in a drawing. Convert Entities upon the sketch to bring it in upon a layer in the drawing view, or simply show it. I've done this before with 3D schematics, or to simply represent something complex such as a chain which I don't care to model properly.
Basically, I don't understand why you would want to import a drawing DWG into a drawing SLDDRW unless you're doing what someone asked you to do (and then my puzzled only transfers to that person instead).
The best way is to create a model in SolidWorks, otherwise why take a drawing and put it into another drawing to put it into another drawing..... on and on........???????
Even if you import to a Solid Part you still need to apply the dimensions to have fully defined sketches..
Creating a model of the project allows for automatic updates, anything less then that is not necessary
Thank you all for your input!! This was thrown at me unexpectedly yesterday. Draft Sight looks to be the best option with what we are trying to accomplish which is making edits to these .dwg. line drawings. Importing these as a new part did not work as only a part of the line sketches would come in.
SolidWorks wont hack it on this one. Thanks again for your help.
Depends which software converted from and how created. Most piping software will save .dwg/.dxf piping as the centerline of the pipe and the flange line inside the file, not the model.
