PDF Export of complex multipage diagrams missing lines

Hi ​@john.a.lopez,

Thank you for posting in the Lucid Community! In order to identify the root cause of the issue you’re experiencing, would you mind attempting the following steps?

1. It’s possible that WebGL is causing an issue with your graphics card.

• Try turning WebGL off by going to View > Rendering > Use WebGL and unchecking the option. For more information on WebGL, check out these resources:
• Troubleshooting: WebGL

• Instructions to webGL on and off in Lucidchart

2. Could you try opening your document in a private or incognito window to help us narrow down the potential cause? For help with opening an incognito window, please see this community post.
3. Could you also try connecting to a different network or disconnecting from your VPN (if applicable)? Sometimes account performance issues can be related to internet security/speed or browser issues. These steps will help us eliminate that possibility.

4. Just to make sure that we are on the same page, please review our Export or print a Lucid document article from the Lucidchart Help Center. Let me know if you have any questions about how downloading/exporting your document should work.

• Once you have reviewed this article, here are some specific things to check when exporting your document:

  • Try the export in a Chrome Incognito browsing session. This often improves performance by clearing your cache and cookies and disabling your extensions.

  • Sometimes issues like this can be related to internet connection speed or network security. Please try the export again on another network, ensuring that you are on a strong, stable connection.

  • Is the page that you are trying to export a Master Page? If so, it will be omitted from the downloaded version of your document and you will need to convert it into a page before exporting. To do this, left-click on your Master Page tab and select "Convert to Page". 

If none of these tips help, would you mind sending me the following details so I can take a closer look at the issue? 

• A description of the download settings (file type, document pages, cropping, quality, etc.) that you selected for the download.

• A screenshot of any error messages or pop-ups that appear when you attempt to export.

• If the document will export but does not look as you expected, please send me a screenshot of the exported filed that is experiencing the issue and a description of what about it is incorrect, or a screenshot of the issue in the exported document.

Let me know if you run into any issues or have any other questions—I’m happy to help!

note that all raster renderings seem OK such as PNG and using slide build for a pptx, no missing lines.

this however is problematic as the desired output for the client is PDF.

I would expect a graphics card issue to not resolve raster images with missing lines as well.

I am not using a VPN during the design sessions.

Hi ​@john.a.lopez,

Thank you for attempting those steps. It sounds like the issue is resolved for now! I’m happy to hear that. If you run into this issue again, feel free to share a temporary Document Support PIN for this document and I will take a closer look. Thanks again for your patience!
