This Dwg File Was Saved By An Application That Was Not Developed Or Licensed By Autodesk

[Rashawn Devegowda]

Somewherealong the line somebody opened up my opened / saved our main drawing template with something other than Autodesk and now the "This DWG file was saved by an application that was not developed or licensed by Autodesk" message is appearing.

Is there any easy way for me to fix the drawing or create a new one completely mirrored so this message stops appearing? For example, is there something similar to the "Import Civil 3D Styles" dialog that will also bring in layers, sheets, text styles, dimension styles, etc?

In windows explorer, navigate to the folder with your template. Right click your template file name, go to properties, previous version tab. Hopefully several will be listed. Open them until you find the one you want. You can then save as and put in a different folder, then copy it over the current one. You can copy it to a new folder and then copy over the current. Or you can try the restore option, never used it so don't know how it works. Always check and double and triple check to be sure you are restoring the best version.

Since today, whenever I try to open either a new file or an old one I get this message: "This DWG file was saved by an application that was not developed or licensed by Autodesk. What do you want to do?". (AS YOU CAN SEE FROM THE SCREENSHOT)

Please describe step by step what you do and how AutoCAD reacts to that (showing dialogs, showing information in command line), this makes it easier for us to understand what happens currently on your system.

I figured that I could used BricsCAD ver 13, until I was done with a project, then save all the drawings using Autocad LT 2012 to get rid of the warning below, but it remains even after I save the drawings using AutoCad.

"Non Autodesk DWG. This DWG file was saved by a software application that was

not developed or licensed by Autodesk. Autodesk cannot guarantee the

application compatibility or integrity of this file."

I don't think that educating the customer in this particular case is going to work here, but setting the variable to 0 seems to give the right result. Unfortunately that would mean running a script on all the drawings to save.

I've started getting the following message. The ONLY cad program I use is AutoCad Lt 2014. I suspect that the culprit is a Windows 10 security update that is preventing AutoCad from embedding crucial information into the file. Anyone have any ideas?

This dialog appears when you open a DWG file that was not produced with an Autodesk product.

Are you 100% sure that this DWG was never saved by someone with a non-Autodesk application?

Regardless, it's nothing more than a marketing message. You can set DWGCHECK to 0, and never have to see it again.

Did that as soon as I posted. my first message. Because this is an issue between Microsoft and Autodesk, I just wanted to call attention to the issue, fully expecting each company to ignore the problem.

AutoCAD is a general drafting and design application used in industry by architects, project managers, engineers, graphic designers, city planners, and other professionals to prepare technical drawings. After discontinuing the sale of perpetual licenses in January 2016,[3] commercial versions of AutoCAD are licensed through a term-based subscription or Autodesk Flex, a pay-as-you-go option introduced on September 24, 2021. Subscriptions to the desktop version of AutoCAD include access to the web and mobile applications. However, users can subscribe separately to the AutoCAD Web App online or AutoCAD Mobile through an in-app purchase.

AutoCAD was derived from a program that began in 1977, and then released in 1979[5] called Interact CAD,[6][7][8] also referred to in early Autodesk documents as MicroCAD, which was written prior to Autodesk's (then Marinchip Software Partners) formation by Autodesk cofounder Michael Riddle.[9][10]

The first version by Autodesk was demonstrated at the 1982 Comdex and released that December. AutoCAD supported CP/M-80 computers.[11] As Autodesk's flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide.[12] The first UNIX version was Release 10 for Xenix in October 1989, while the first version for Windows was Release 12, released in February 1993.[13][14]

ESRI ArcMap 10 permits export as AutoCAD drawing files. Civil 3D permits export as AutoCAD objects and as LandXML. Third-party file converters exist for specific formats such as Bentley MX GENIO Extension, PISTE Extension (France), ISYBAU (Germany), OKSTRA and Microdrainage (UK);[15] also, conversion of .pdf files is feasible, however, the accuracy of the results may be unpredictable or distorted. For example, jagged edges may appear. Several vendors provide online conversions for free such as Cometdocs.

AutoCAD and AutoCAD LT are available for English, German, French, Italian, Spanish, Japanese, Korean, Chinese Simplified, Chinese Traditional, Brazilian Portuguese, Russian, Czech, Polish and Hungarian (also through additional language packs).[16] The extent of localization varies from full translation of the product to documentation only. The AutoCAD command set is localized as a part of the software localization.

There are a large number of AutoCAD plugins (add-on applications) available on the application store Autodesk Exchange Apps.[17]AutoCAD's DXF, drawing exchange format, allows importing and exporting drawing information.

For example, AutoCAD Architecture (formerly Architectural Desktop) permits architectural designers to draw 3D objects, such as walls, doors, and windows, with more intelligent data associated with them rather than simple objects, such as lines and circles. The data can be programmed to represent specific architectural products sold in the construction industry, or extracted into a data file for pricing, materials estimation, and other values related to the objects represented.

Additional tools generate standard 2D drawings, such as elevations and sections, from a 3D architectural model. Similarly, Civil Design, Civil Design 3D, and Civil Design Professional support data-specific objects facilitating easy standard civil engineering calculations and representations.

Softdesk Civil was developed as an AutoCAD add-on by a company in New Hampshire called Softdesk (originally DCA). Softdesk was acquired by Autodesk, and Civil became Land Development Desktop (LDD), later renamed Land Desktop. Civil 3D was later developed and Land Desktop was retired.

AutoCAD's native file formats are denoted either by a .dwg, .dwt, .dws, or .dxf filename extension. .dwg and, to a lesser extent, .dxf, have become de facto, if proprietary, standards for CAD data interoperability, particularly for 2D drawing exchange.[31]

The primary file format for 2D and 3D drawing files created with AutoCAD is .dwg. While other third-party CAD software applications can create .dwg files, AutoCAD uniquely creates RealDWG files.[32] The drawing version code changes between AutoCAD releases.[33]

AutoCAD WS began with a version for the iPhone and subsequently expanded to include versions for the iPod Touch, iPad, Android phones, and Android tablets.[38] Autodesk released the iOS version in September 2010,[39] following with the Android version on April 20, 2011.[40] The program is available via download at no cost from the App Store (iOS), Google Play (Android) and Amazon Appstore (Android).

AutoCAD is licensed, for free, to students, educators, and educational institutions, with a 12-month renewable license available. Licenses acquired before March 25, 2020 were a 36-month license, with its last renovation on March 24, 2020.[44] The student version of AutoCAD is functionally identical to the full commercial version, with one exception: DWG files created or edited by a student version have an internal bit-flag set (the "educational flag"). When such a DWG file is printed by any version of AutoCAD (commercial or student) older than AutoCAD 2014 SP1 or AutoCAD 2019 and newer, the output includes a plot stamp/banner on all four sides. Objects created in the Student Version cannot be used for commercial use. Student Version objects "infect" a commercial version DWG file if they are imported in versions older than AutoCAD 2015 or newer than AutoCAD 2018.[45]

I was granted a license of Fusion 360 to play with and I find it does not export STL files. Seems they finally fixed that. I'd like to import a model into PrusaSlicer. The only formats I find are f3d, igs, iges, sat, smt, stp, step, usdz. Is there anything there that PS will grok?

Fusion can of course export STL files. The easiest way to do it is to right-click on the component or body in the component browser, then select Save as Mesh. Here you can choose between 3MF and STL, both of which Prusaslicer understands.

I saw that in the autodesk support area. Odd that my application does not have that option. v2.0.12376, I guess they finally fixed that "STL old/bad" problem. I found another comment somewhere that under "Utilities/MAKE/3D Print" you could send STL to an app. I guess that's one say to get there with this version. I'll install PS over on the win10 and see if that works. But really I was wondering if PS could handle any of these other formats. Doesn't look like it.

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

No idea why you're not seeing it. I'm on 2.0.12376 as well, and this has been in Fusion since times immemorial. See screenshot (EDIT: Click on the image. The thumbnail cut off the pertinent part). Right click on a body or component.

they only offer these in my particular install, f3d, igs, iges, sat, smt, stp, step, usdz. I wonder if I need to install some extension. I'll go to the autodesk forums and ask around. I'm a newbie to it, so I don't know what I'm doing, but it seems like an export or save as isn't rocket surgery.
