What is the best practice for converting fake DWG to Autodesk DWG, taking AutoCAD version 2013 into account?
In this case the fake DWG only has model space data (has no paper space layouts)
Which one of these is best or is there another method?
Open the fake DWG in Acad. Set its units correctly. Save and Close it.
Start a new DWG based on your company template, use the INSERT command (with explode enabled) to import the fake DWG at 0,0, scale 1, rotation 0.
Save the new DWG.
Open the fake DWG in Acad. Set its units correctly.
Start a new DWG based on your company template.
Use the Clipboard to copy the objects from the fake DWG to the new DWG.
Save the new DWG.
Use DWG TrueView 2013 to create a new DWG from the fake DWG.

Can you explain what you mean by a 'fake' DWG? Are you referring to a dwg file created/edited by a non-autodesk product? If so, does that drawing file conform to the OpenDWG standard published by the ODA?
Follow up ... before accepting the solution as Exploded INSERT...
Can anyone explain WHY this is better than the other 2 options presented? In simple terms please.
CAD Users will have a different opinion on this one, thats for sure. Most users would like to interpret DWG as a common CAD file format that could be used for exchange between CAD systems. I am going to stick my neck out (and probably get it chopped off), in my humble, almost meaningless, unqualified opinion in terms of the question asked in this post, DWG is a product of an Autodesk software application - including RealDWG (if it stil exists). Fake DWG is a DWG created by a non Autodesk software application or created without using the Autodesk RealDWG 'facility' - in AutoCAD terms - a non-trusted DWG file is what I termed a 'fake' DWG. And .. u are correct I should stick to correct terminology, I deserve to be punished. I should not have used the word fake, I should have used: non-trusted.
I have been using AutoCAD since 1990. I always use Exploded INSERT in AutoCAD to 'clean' untrusted DWG. Just because I always have done it this way. Sometimes there are undocumented improvements, sometimes I dont read enough. So, I wondered if this is still the correct method in 2013 Acad. And ... why is it better than other methods?
Thanks for taking time to reply. These forums prove to be invaluable to users throughout the World.
Have a great day.
Your template file is already set up they way you want it: by INSERTing a file into your template, it inherits the content already in place (how autocad treats inserted objects). Basic AutoCAD 101 behaviour you need to take advantage of, instead of constantly editing and changing other files internally and never quite getting it all correct.
I would wblock the contents of the drawing into a new drawing and insert that into you company template.
When creating the wblock make sure that you use the "select objects" option rather than "Entire drawing" so you avoid inserting anything that is not visible or needed. This can help reduce bad data being copied to the new drawing.
Once you have inserted it into the template and exploded it I would purge the drawing and audit it (also use -PURGE to remove and regapps).
It would then be a good idea to ensure the entities in the drawing have the colors, linetype, etc set to ByLayer rather than being individually set. Also make sure the ltscale for all objects is set to something sensible.
I used to prefer just inserting the original drawing, easy, stable command, done.
The problem is that any and all styles (text, dimentions etc) will come with, even if not in use. Thus copy/paste or wblock are a good solution, since they will only bring what is actually being used in the drawing.
Another problem we've had to deal with is blocks in the drawing with the same name as our blocks, but different definitions. In that case as soon as you do any of the above methods, the blocks are defined as per your template when they land in there, and can look pretty crazy if it's the wrong block. Here's what I use to get around that:
1. Make a drawing from your simple acad template, no styles, no blocks etc.
2. Copy/paste (or I guess use the wblock method) from wherever into this drawing
3. Make a new drawing from your company template, save as drawing1 or whatever on your desktop
4. Insert drawing1 into your drawing.
This way you will get all your styles and blocks from your template, but without overwriting any duplicated names.
