CAD floor plans

Import the plant's DWG or DXF drawing as a background and draw the AGV network on top of it at the right scale. The floor plan is only visual: it never affects routing, snapping, selection or traffic.

Importing a drawing

Open the Background tab in the side panel (available in Draw and Simulate).
Choose the units. Original drawing units defaults to Automatic · file units, which uses the unit declared in the CAD file. Choose millimetres, centimetres, decimetres, metres, kilometres, inches or feet to override it. If the file declares no unit and you did not choose one, the app asks you.
Import. Click Import floor plan and select a .dwg or .dxf file. The app reads the file, analyses layers and prepares the visible content. Large drawings can take a few minutes; Stop import is always available.
Check the preview. The preview shows the Applied units. If something is missing or too much is included, press Change content, adjust the selection, and press Prepare preview.
Confirm. Press Use floor plan. The drawing is placed with its lower-left corner at (0, 0) and becomes part of the project.

Example: a drawing in metres declared as inches

If a 3 m corridor measures about 8 cm, the file probably declares the wrong unit (one inch is 25.4 mm, one metre is 1000 mm). Import again and choose Metres: 3.1 drawing units become 3100 mm. After importing, you can also correct the size with the scale factor.

Display formats

Three ways to display the floor plan are available under Advanced options. The default suits almost every drawing.

Format	When to use it
Accelerated vector · recommended	Default. Geometry is prepared in the background, grouped and drawn by the graphics card, with repeated blocks reused. Sharp at any zoom. Requires WebGL.
Image · 1 cm detail	When WebGL is unavailable. The drawing is converted to PNG tiles at 10 mm per pixel; details below one centimetre cannot be distinguished. Resolution is never reduced silently.
Vector · small drawings	Simple vector display for small drawings, with stricter limits.

Reading method offers Automatic (DWG read locally with LibreDWG WebAssembly, DXF read in a worker) or Local alternative, which needs ODA File Converter installed on the server; it is not included in the standard online service, so it may be unavailable. Reading happens in your browser or on the studio's own server: no drawing is sent to external conversion services, and the original file is never modified.

Text and CAD recovery

These options, applied before Prepare preview, help with difficult files:

Import text and Text size relative to CAD (25–200 %), to exclude texts or resize them independently of the plan;
Recover hatch outlines, which draws HATCH boundaries as outlines (fills and patterns are not reproduced);
Interpret zero normals on the XY plane, for entities exported without a valid normal.

The Import results report groups what happened: recoveries applied, import selections, approximate appearance (for example substitute fonts) and items that need review (for example missing external references).

Adjusting the background

Show floor plan and Opacity are always available.
Position and content collects the offset of the drawing and the visibility of individual layers, including layers inside blocks.
Move to origin places the lower-left corner of the drawing at (0, 0), useful for projects imported before this became automatic.
Remove floor plan deletes the background from the project (undoable).

Scale factor

Scale factor corrects the size after import: 1 keeps the imported size, 0.5 halves it, 2 doubles it. Confirm with Enter or by leaving the field. The factor is absolute relative to the import, the lower-left corner stays fixed, and it works for every format. Paths, stations and annotations never move with the background.

Toggling layers from the canvas

With an accelerated vector background, the rail in Draw shows a Layers tool. Click an element of the floor plan to see its layers and switch them off or on. Show all layers restores the full drawing; Done or Esc closes the tool. Layer lists are sorted alphabetically with natural number order.

What is supported

2D model space plans: lines, polylines, arcs, circles, ellipses, points, blocks and dimension graphics already contained in the file. Texts respect nominal height, box width and direction; fonts and formatting are approximated with the bundled fonts (Latin, Greek, Cyrillic and symbols).

Not supported or partially supported: WIPEOUT masks (objects they cover may show; hide the affected layers), non-standard OCS planes, splines, images and 3D objects, and external references (XREF) whose geometry is not embedded in the file. Print viewports are not part of the model space plan.

Limits and performance

Item	Limit
Source file	DWG or ASCII DXF up to 100 MB (binary DXF is not supported). The saved project, background included, must also stay within 100 MB.
Accelerated vector scene	Up to 128 MiB of encoded buffers and 512 MiB of decoded geometry, plus browser and GPU memory.
Image mode	10 mm per pixel, up to 2048 tiles and 128 MiB of encoded images.

The prepared background is compressed losslessly and stored in the .sim project, the draft and the undo history, so reopening a project never requires the original DWG. Not every DWG or DXF can be opened: for very large or unusual files, work on a simplified copy in your CAD tool.
