The TLC Gym Designer lets church staff lay out events in the gym before setup day — arranging tables, chairs, the stage, and other equipment, and checking seat counts and inventory as you go. Access is limited to church Google accounts: sign in with a tlctulsa.org or lcatulsa.org address.
When you choose New Project and name it, the app creates a folder with that name in the church's shared Google Drive. From then on, every layout you save for that event is stored inside its folder, so you (or anyone on the team) can reopen it later from Open Existing Project.
Each time you save, the app writes two files under the same revision name — a .json (the editable layout data) and a .pdf (a printable floor plan).
You never have to name individual save files — the app does it for you from the project name plus a revision tag. Say you create a project called Easter Sunday 2025:
R0 means Revision 0 — your very first saved version. The number bumps up by one every time you save again (R0 → R1 → R2 …), so nothing gets overwritten and you keep a full history. Need to go back to an earlier arrangement? Just load that revision from the Saved Layouts list.
Once you're inside the designer, click the Tutorial button in the top-left corner of the canvas for a step-by-step walkthrough of building a layout.
Inventory limits control how many of each piece of equipment can be placed in a layout. Only authorized staff should change these values.
Set the upper bound for each item. Users will be blocked from placing more than the limit and will see a notice. Changes save to this device immediately.
