I was wondering if anyone encountered what seems to be file size limits for Solidworks assemblies in Edrawings 2020 or EDrawings Pro 2020 ?
I seem to get a fatal error when I approach 700 Mo.
Thank you for your help !
I have not experienced or seen any file size limits with eDrawings
Have you tried oppening a file larger than 700 Mo ?
Geez, what kind of assembly do you work with for them to get to 700MB? I work with large assemblies of a trailer which can reach 300 different components and 10 000 total parts and don't get anywhere near this number. 10MB is more like it.
We are a bus manufacturing company, so a bus, with a total of components and large imported models I would rather not count
I'm sure there has to be something wrong within your assemblies or drawings, such as image quality. A bus and a trailer do not differ that much in terms of total components and imported models.
For example, this is a 8MB master assembly(section made to show more clearly interior:
You are right, I am mistaken. I am not talking about a Edrawings file that is 700 Mb. Ours are approximately 180 Mo. The problem arrises when we try opening 700 Mb Solidworks Assembly files, especially since that is the only model type we can open in EDrawings VR.
Still, that is some huge file size Guillaume. You must have some sort of performance hit from such huge file sizes. Are you sure these are normal? I would advise running the performance tool inside the assembly to see what could be optimized. Image quality, differing SolidWorks versions between files and also having multiple appearances in parts can impact these.
Performance evaluation is a great tool to help with this

No worries, we are using a lot of tools to make sure our assemblies stay healthy and useable. We use SpeedPak configurations a lot, instead of losing a lot of time making simplified assemblies, and simplifying supplier models. Any idea about the 700Mb Edrawings limit ?
I've never heard of a file size limit, but 700MB is one hell of a file to work with. Could you share a screen of the assembly on SolidWorks? I have a hard time grasping why your file is so large, especially if you do use simplified assemblies and supplier models.
Have you tried letting it open over night to see if it does eventually open? IMO either the process takes forever to do so or the process reaches it's time limit for the operation without completing it and stops responding.
Do you have a multitude of configurations spanning through multiple assembly levels? This could also be one of the cause of your large file size.
I cannot share my assemblies or any images, as this project is not public yet.
For the "simplified models" we are using, they are not. SpeedPak assemblies simplify the geometric and readily available data (such as file hierarchy, feature trees), but keeps all the graphic. These large file sizes relate to a lot of visual data.
For the crash, it happens immediatly. See the image below. Excuse the french message :
Thank you for your help.
Sounds to me like your files have analysises on them from reading the first error message. Motion or stress, I don't know. I'm not an engineer but as far as I'm aware all engineers I have worked with have made their analysises on seperate models from the ones being produced. I'm guessing analysises tend to crump up a file.
No worries about the french, I have that issue too
No analysis saved in the file, and again, same file with one assembly suppresed (any one of them) at 687Mo works fine. As soon as it reaches 700 Mo or more, those two messages pop up and then nothing.
Have you contacted your VAR about this? They would be the one best placed to answer specific issues like this
I do not have technical support from my reseller, but will change soon. We'll see then.
Is it an actual crash or are the two error dialogs displayed and the document simply doesn't open?
That error can be caused by not saving tessellation data in your part models. Is this option enabled for all your parts?
Exactly as you said in the second option, the two error dialogs display and the document simply doesn't open.
For the tesselation, it is overwritten by large assembly mode, and when removed I still can't unselect. Since EDrawings uses the tesselation data, I wonder what will open if I can save with this option disabled, which I can't...
This is a part level setting, not an assembly level setting.
Then I dont think it would change the assembly file size
Individual files properties impact assembly file size, which is why I was suggesting looking up your image quality while using the performance evaluation tool.
Take a bolt and reduce image quality on the part and then save the assembly. Assembly will be faster and smaller in file size.
