Hi ​@atsalolikhin_tm 

Thanks for posting in the Lucid Community!

Lucidchart only supports specific diagrams using Mermaid code. Unfortunately, architecture diagrams are not currently supported in Lucidchart. To see the list of supported diagrams, please visit our Diagram as code with Mermaid in Lucidchart article. In addition, if you would like to see example syntax for these diagrams, check out this Community post.

Also, we’re very interested in your feedback and committed to continually improving our products. We would love to hear about your idea to add architecture diagrams to the list of supported diagrams in Lucidchart. Please first search the Product Feedback section of this community (with the filter Topic Type = Idea) to see if it’s already been submitted. If so, please add any additional details you’d like and upvote the request - this consolidation helps to refine feedback and properly capture the popularity of the request.

If no one has submitted this idea yet, please create one of your own and be sure to include details about your use case or what you’d like to see in this experience. This will also allow other users with similar requests to discover and upvote it, then add details of their own.
