Canvases

Canvases

A Canvas is a single drawing sheet within a SkyCiv CAD project. Every project contains at least one canvas, and you can add as many as you needone per floor level, one per detail, or one per drawing sheet.

Canvases are managed from the Canvas accordion in the left sidebar. Each canvas stores its own geometry, annotations, and layer data independently.



The Canvas Panel

All canvas management is done from the Canvas accordéon, found in the left sidebar. Clique le Canvas header to expand it. The panel lists every canvas in the project and provides controls for adding, switching, renaming, reordering, copying, and deleting canvases.

The currently active canvas is highlighted in the list. Only one canvas is active at a timeall drawing tools operate on the active canvas.



Basic Operations

Add a Canvas

Create a new, blank drawing sheet in the project

Clique le Add New Canvas button at the bottom of the Canvases panel. A new blank canvas is created and immediately made active.

Pas à pas

  1. 1les données d'entrée pertinentes pour le signe sont préréglées lorsque vous ouvrez le Canvases accordion in the left sidebar.
  2. 2Cliquez sur Add New Canvas at the bottom of the panel.
  3. 3The new canvas appears in the list and becomes the active canvas.
💡

Pointe: New canvases are named Canvas 2, Canvas 3, etc. par défaut – rename them immediately to keep the project organised.

Switch Between Canvases

Move to a different drawing sheet

Click anywhere on a canvas row in the Canvases panel to make it active. The current canvas is saved automatically before switching, so no data is lost.

💡

Pointe: The active canvas row is highlighted in the list. Any selection on the previous canvas is cleared when you switch.

Rename a Canvas

Give a canvas a meaningful name for easier navigation

Click directly into the name field on a canvas row to edit it inline. Type the new name and press Entrer or click away to confirm. Canvas names must be unique within the projectduplicates are automatically resolved.

💡

Pointe: Use descriptive names like Ground Floor Plan, Roof Detail, ou Section A-A to keep multi-canvas projects navigable.

Copie (Dupliquer) a Canvas

Create an exact copy of an existing canvas

Clique le duplicate icon (two overlapping squares) on any canvas row. A full copy of that canvasincluding all geometry, annotations, and layer assignmentsis inserted directly after it in the list.

💡

Pointe: Copying is a quick way to create a new floor level that shares the same column grid – dupliquer, then modify only what changes.

Delete a Canvas

Permanently remove a canvas and all its content

Clique le red trash icon on a canvas row and confirm the prompt. Deletion is permanent and removes all geometry, annotations, and layer data on that canvas. A confirmation dialog is shown by default – Chèque Don’t ask again to skip it in future.

⚠️

Remarque: The trash icon is disabled when only one canvas remainsa project must always have at least one canvas. Deletion cannot be undone.

Reorder Canvases

Change the position of a canvas in the list

Utilisez le haut et down arrow buttons on each canvas row to move it earlier or later in the list. Arrow buttons are only visible when the panel is in Hierarchy commande – they are hidden when Sort by Elevation is active (elevation order is controlled by the elevation value, not manual position).

💡

Pointe: If the arrow buttons are missing, basculer Sort by Elevation off to return to hierarchy mode where manual ordering is available.



Elevation and Sort Order

When a project represents a multi-storey structure, each canvas can be assigned an élévation value that places it at the correct height in the 3D structural model (S3D export). The canvas list can be sorted either by these elevation values or in a custom manual order.

Sort by Elevation Toggle

Switch between elevation order and custom hierarchy order

Ce logiciel Sort by elevation toggle at the bottom of the Canvases panel switches between two display modes:

  • Sort by Elevation (sur): Canvases are ordered from lowest to highest elevation. Un Décalage column appears showing each canvas’s elevation value. This order mirrors how canvases will be stacked in the S3D 3D model export.
  • Hierarchy (off): Canvases appear in a custom order that you control with the up/down arrow buttons. Canvas groups (master/child) show their indented hierarchy here.
💡

Pointe: Canvases without an assigned elevation appear at the bottom of the list in elevation mode, sorted by their internal index.

Canvas Elevation

Assign a height value used when exporting to the 3D structural model

Quand Sort by Elevation is on, un Décalage column appears. Canvases without an elevation show a + bouton – click it to assign one. Canvases with an elevation show an editable number field.

The elevation value determines how high each floor is placed in the 3D structural export. The unit matches the project length unit (mm, cm, m, pi, in).

Pas à pas

  1. 1Activer Sort by Elevation to show the Offset column.
  2. 2Clique le + button next to any canvas to assign it an elevation.
  3. 3Type the elevation value and press Entrer to confirm. The list re-sorts automatically.
💡

Pointe: Assign elevation 0 to the ground floor canvas. Suggested values for new canvases are automatically set to 3000 mm above the highest existing elevation.



Canvas Groups (Master / Enfant)

When multiple floor levels share the same structural layout (par exemple. identical column grids across several floors), you can link them into a canvas group. One canvas becomes the Master and the others become Enfants.

Structural changes made to the master can be propagated to all children in one click, keeping repeat floors in sync without manually copying geometry.

In the canvas list, the master is labelled M and children are labelled Faire glisser de gauche à droite sélectionnera tout ce que la zone de sélection touche, both coloured with a shared group accent colour.

Link Canvases into a Group

Designate a master canvas and link child canvases to it

Cliquez sur Link Canvases at the bottom of the Canvases panel to open the linking wizard. Select which canvas will be the master and which canvases will be its enfants. Confirm to create the group.

Pas à pas

  1. 1les données d'entrée pertinentes pour le signe sont préréglées lorsque vous ouvrez le Canvases panel and click Link Canvases.
  2. 2Choose the master canvas from the wizard.
  3. 3Select one or more child canvases to link to it.
  4. 4Confirm to create the group. Ce logiciel M / Faire glisser de gauche à droite sélectionnera tout ce que la zone de sélection touche labels and accent colour appear in the list.
💡

Pointe: Dans Hierarchy vue, master groups can be collapsed and expanded using the triangle toggle next to the master canvas row.

Propagate Structural Changes

Push master canvas structural updates to all linked children

When structural geometry on a master canvas changes, un amber highlight appears on the master row and its children to signal the group is out of sync. Clique le propagate button (share icon) on the master row and confirm to push the updated structural data to all child canvases.

⚠️

Remarque: Propagation overwrites structural data on child canvases. This action cannot be undone. Non-structural content on children (annotations, dimensions, revision clouds) is preserved.

Remove a Child from a Group

Detach a child canvas so it no longer receives propagated updates

Clique le chain-broken icon on a child canvas row and confirm the prompt. The canvas is removed from the master group and becomes an independent canvas. Its existing geometry is retainedit simply stops receiving future propagated updates from the master.

💡

Pointe: Removing a child does not delete or modify its contentit only breaks the link to the master. You can re-link it at any time using Link Canvases.
