Quodsi for Lucidchart

Quodsi for Lucidchart is in early access. It adds Quodsi to the Lucidchart editor, so you can turn the process maps you already keep there into simulation models.

Who it suits

Choose this if your process maps live in Lucidchart and you don't want to move them. To ask for access, go to the support page.

If you want to start today, Quodsi for draw.io is available now.

Signing in

Open the Quodsi panel. If you're signed out, click Sign In in the strip at the top of the panel, then Sign in. Lucidchart then asks for your Quodsi account details.

You need to be signed in to run simulations. The AI Advisor buttons only appear once you are.

Drawing and converting

Draw your process with ordinary Lucidchart shapes and lines. When you're ready, you have three ways to convert the page:

Choose Convert Diagram to Model from the Quodsi menu.
Click Convert Diagram to Model on the Get started card in the panel.
Click Review & convert first… on the same card to preview and edit the mapping before you convert.

The review step is only in Lucidchart. In all cases Quodsi reads how your shapes connect:

On your diagram	Becomes
A line attached to a shape at both ends	A Connector
A shape with lines going out and none coming in	A Generator, where work enters the process
A shape with at least one line coming in	An Activity, a step in the process
A shape with no lines	Skipped

To change what a shape is, select it and use the type dropdown at the top of the panel. A shape can be None, Activity, Generator or Resource, and a line can be None or Connector. Resource only appears in the Intermediate and Advanced complexity views.

Swimlanes A swimlane lane can stand for a Resource. Select the lane and link it to a resource in the panel. Each resource can belong to only one shape or lane.

The Quodsi menu

Quodsi has its own menu in Lucidchart. Some items only appear when they apply to the page you're on.

Menu item	When you see it	What it does
Convert Diagram to Model	On a page that isn't a model	Turns the page into a model.
Remove Quodsi Model	On a model page	Turns the page back into a plain diagram. See the warning under Saving your work.
Diagram Mapping	On a model page	Opens the screen that shows how your shapes map to the model.
Take the Tour	Always	Starts the guided tour.
Status	Always	Shows whether Quodsi's services are running.
Feedback & Support	Always	Opens Settings at its Help section.

Examples and the tour

Lucidchart has no example picker. Take the Tour adds a page called "Airport Security (example)" to your document, and leaves your other pages alone. To browse all the published models, use draw.io.

Saving your work

Your model is stored in the Lucidchart document, on the page you converted. There's no separate save step for Quodsi. Your scenarios, studies and results are stored by Quodsi on its servers.

Remove Quodsi Model cannot be undone. It removes the Quodsi data on the page and every shape. It also removes the model with its Simulation Project, studies and scenarios, and it permanently deletes the simulation results.

Where the Quodsi panels are

The panel is called Quodsi Model, and it opens in Lucidchart's right dock.

Account strip: the top row, with your account, your Settings gear and sign-in.
On a model page: the orange What-if Analysis button and the Advisor button.
With a shape selected: the type dropdown and that shape's editor.

What-if Analysis, the AI Advisor and Settings each open in a separate Lucidchart window on top of your document. Settings has a Window size section if you want them larger.

When Quodsi is updated

If your copy is out of date, you'll see this message: "Quodsi has been updated. Reload LucidChart to get the latest version." Reload the Lucidchart tab to clear it.
