File Management

Save, load, and manage your structural models in AutoCalcs. Your work is preserved between sessions, and signed-in users get cloud sync across devices.

Opening the File Manager

Click the folder icon in the top-left corner of the ribbon, or press Ctrl+O to open the File Manager dialog.

AutoCalcs automatically saves your current model to browser local storage as you work. To save a named project:

  2. Enter a name for your project
  3. Click Save

The project name appears in the top ribbon. An asterisk (*) indicates unsaved changes.

Loading Models

To open a previously saved model:

  3. Click Open or double-click the project

Local vs Cloud Storage

Projects can be stored locally in your browser or in the cloud:

Local Storage

  • Local files are marked with an orange Local tag in the File Manager
  • Stored in your browser's localStorage - clearing browser data will delete them
  • Only accessible on the device and browser where they were created
  • No account required

Cloud Storage (Sign In Required)

  • Cross-device access - Access your projects from any computer
  • Persistent storage - Projects won't be lost if you clear browser data
  • Secure - Your work is stored safely in the cloud

Sign in to save projects to the cloud. Remember to save regularly - cloud projects are updated when you click Save.

File Manager Toolbar

The File Manager includes a toolbar with additional features:

  • New / Folder - Create a new project or folder to organise your files
  • Copy / Cut / Paste - Duplicate or move projects between folders
  • Import / Export - Import projects from JSON files or export for backup and sharing
  • Delete - Remove selected projects or folders
  • Search - Filter projects by name
  • Sort - Order files by name or date
  • View modes - Switch between list, grid, and thumbnail views

DXF Import

Import existing geometry from CAD by loading a DXF file. Line entities in the DXF are converted to nodes and members with:

  • Automatic node merging - Nodes within 1mm tolerance are merged into a single node
  • Duplicate detection - Overlapping members are detected and removed

To import a DXF, use the Import button in the File Manager toolbar and select your .dxf file. The wireframe will appear as nodes and members ready for section/material assignment and analysis.
