Blocksare reusable drawing components – a named collection of geometry that can be placed on the canvas multiple times as lightweight instances. Editing the block definition automatically updates all placed instances.
Χρησιμοποιήστε το Block Reference πίνακας (right-side accordion) to create, insert, επεξεργασία, and manage blocks.
Concepts
Block Definition – The template that stores the geometry and a namedbase point (προέλευση). Changing the definition updates every instance placed on the canvas.
Block Instance – A lightweight reference to a block definition placed at a specific position, with an independent scale and rotation. Instances share the same geometry data – they do not duplicate it.
Σημείο βάσης – The local origin of the block. When you place an instance, the base point aligns to your clicked position on the canvas.
Block Reference Panel
ο Block Referenceaccordion on the right-hand sidebar contains all block controls. Click the accordion header to expand it. The header shows a count of defined blocks in parentheses.

Block Name
Text field for naming a new block definition. Duplicate names are auto-incremented (Block, Block1, Block2…).
Σημείο βάσης
Χ,Y coordinate field for the block origin. Type coordinates (π.χ. 100, 50) ή χρήση Διαλέγωto click a point on the canvas.
Διαλέγω
Activates a crosshair cursor. Click anywhere on the canvas to set the base point coordinates.
Δημιουργώ / Προσθήκη
ShowsΔημιουργώwhen geometry is selected (creates a new block). ShowsΠροσθήκηwhen a block is selected in the list (places a new instance).
Select All Instances
Selects every canvas instance of the currently highlighted block definition.
Επεξεργασία
Enters edit mode for a single selected block instance. Only available when exactly one instance is selected.
Update
Saves changes made during edit mode back to the block definition, updating all instances.
Ματαίωση
Discards all changes made during edit mode and restores the original block definition.
Ανατινάζω
Converts selected block instances back into individual canvas objects at their world positions.
Αφαιρώ
Deletes the selected block definition (and all its instances) or removes selected instances from the canvas.
The block list below the controls shows all defined blocks with their instance count (π.χ. Column Detail | 4 instances). Click a row to select that block definition.
Create a Block
Create Block Reference
Convert selected geometry into a named, reusable block
Shortcut Right-click → Create Block Reference
Select any geometry on the canvas, then use the Block Reference panel or the right-click context menu to convert the selection into a reusable block. The original geometry is removed from the canvas and replaced with a block instance at the same location.

4Κάντε κλικ Δημιουργώ. The block definition is added to the list and one instance is placed on the canvas.

Υπόδειξη:You can also right-click any selection and chooseCreate Block Reference – it uses the same flow and auto-populates a default name if the Block Name field is empty.
Insert Block Instances
Place Block Instance
Place one or more copies of a block onto the canvas
Once a block is defined, you can place as many instances as needed. Each instance is independent – it has its own position, περιστροφή, and scale – but shares the same underlying geometry with all other instances of that block.

1In the Block Reference panel, click the block name in the list to select it.
2Κάντε κλικ Προσθήκη. The cursor enters placement mode.

💡
Υπόδειξη:Active snap settings apply during placement – use endpoint, midpoint, or grid snaps to position instances precisely relative to other geometry.
Edit a Block
Edit Block
Modify block geometry – changes propagate to all instances automatically
Context menu Right-click → Edit Block
Block edit mode lets you modify the geometry inside a block definition. While in edit mode, the block’s contents are displayed as editable canvas objects. Any geometry tools (γραμμή, τόξο, κείμενο, διάσταση, και τα λοιπά.) can be used to add or modify the block’s content. Saving the changes updates every instance of that block on the canvas.

Entering edit mode
1Click a single block instance on the canvas to select it.
2Κάντε κλικ Επεξεργασίαin the Block Reference panel, or right-click and chooseEdit Block.
3The block’s geometry appears as editable items. A bounding highlight shows the block boundary.
4Draw new geometry or modify existing items inside the block. You can also update the base point usingΔιαλέγω.
5Κάντε κλικ Updateto save and exit edit mode – all instances reflect the changes immediately. Κάντε κλικ Ματαίωσηto discard changes and exit.
✅
Update vs Cancel:Updatesaves the new geometry to the block definition and refreshes all instances. Ματαίωσηrestores the original definition – any geometry drawn during edit mode is discarded.
⚠️
Σημείωση:Undo and Redo are disabled while in block edit mode. Exit edit mode first (μέσω Update ή Ματαίωση) before using Undo/Redo.
Explode a Block

Convert block instances back into individual editable objects
Ανατινάζωconverts one or more selected block instances into their constituent geometry. The geometry is placed at the correct world-space position (factoring in the instance’s position, περιστροφή, and scale). The block definition remains in the library – only the selected instances are affected.

⚠️
Σημείωση:Exploding is destructive – the instance link to the block definition is broken. If you later edit the block definition, exploded geometry will not be updated. Use Undo if you exploded accidentally.

Συμβουλές & Σημειώσεις
💡
One edit, many instances:Edit the block definition once and every instance on the canvas is updated automatically – no need to manually revise each copy.
💡
Unique names:Block names must be unique. If you enter a name that already exists, a numeric suffix is added automatically (Block, Block1, Block2…).
💡
Base point matters:The base point is the “handle” used for placement. Set it to a meaningful location – π.χ. the bottom-left corner of a detail, or the centre of a bolt pattern – to make insertion snapping predictable.
💡
Select All Instances: Χρησιμοποιήστε το Select All Instancesbutton to select every instance of a block at once – handy for bulk moves, layer changes, or exploding all copies together.
💡
Filter selection: Στο Επιλογή φίλτρου διαλόγου, enable or disable theBlockscheckbox to control whether block instances are selectable during box or click selection.
💡
Saved in the file:Block definitions and instances are saved with the canvas JSON. When you share or reload a file, all blocks and their instances are fully restored.
