Blocks

Blocks

Blocks are 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.

使用 Block Reference パネル (right-side accordion) to create, insert, 編集, and manage blocks.

Concepts

Block Definition – The template that stores the geometry and a named base point (元). 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.

基点 – 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

の Block Reference accordion 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.

Panel Controls

コントロール 説明
Block Name Text field for naming a new block definition. Duplicate names are auto-incremented (Block, Block1, Block2…).
基点 バツ,Y coordinate field for the block origin. Type coordinates (例えば. 100, 50) または使用します 選ぶ to click a point on the canvas.
選ぶ Activates a crosshair cursor. Click anywhere on the canvas to set the base point coordinates.
作成 / 追加 Shows 作成 when geometry is selected (creates a new block). Shows 追加 when a block is selected in the list (places a new instance).
Select All Instances Selects every canvas instance of the currently highlighted block definition.
編集する 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.
キャンセル Discards all changes made during edit mode and restores the original block definition.
爆発する Converts selected block instances back into individual canvas objects at their world positions.
削除する 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 (例えば. 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.

Step-by-step

  1. 1Select the geometry you want to group into a block (行, メーカーのウェブサイトからDXFファイルを入手する, テキスト, 寸法, hatches, 等).
  2. 2を開きます Block Reference accordion and type a name in the Block Name 分野.
  3. 3を設定します。 基点: type X,Y coordinates directly, またはをクリックします 選ぶ and click a point on the canvas (例えば. the corner or midpoint of the geometry).
  4. 4クリック 作成. The block definition is added to the list and one instance is placed on the canvas.
💡

ヒント: You can also right-click any selection and choose Create 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, 回転, and scale – but shares the same underlying geometry with all other instances of that block.

Step-by-step

  1. 1In the Block Reference panel, click the block name in the list to select it.
  2. 2クリック 追加. The cursor enters placement mode.
  3. 3Click on the canvas to place an instance. The block’s base point aligns to the clicked position.
  4. 4Continue clicking to place more instances. 押す ESC またはをクリックします 追加 again to exit placement mode.
💡

ヒント: 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 (ライン, アーク, テキスト, 寸法, 等) 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

  1. 1Click a single block instance on the canvas to select it.
  2. 2クリック 編集する in the Block Reference panel, or right-click and choose Edit Block.
  3. 3The block’s geometry appears as editable items. A bounding highlight shows the block boundary.
  4. 4Draw new geometry or modify existing items inside the block. You can also update the base point using 選ぶ.
  5. 5クリック Update to save and exit edit mode – all instances reflect the changes immediately. クリック キャンセル to discard changes and exit.
✅

Update vs Cancel: Update saves the new geometry to the block definition and refreshes all instances. キャンセル restores the original definition – any geometry drawn during edit mode is discarded.

⚠️

注意: Undo and Redo are disabled while in block edit mode. Exit edit mode first (経由 Update または キャンセル) before using Undo/Redo.

Explode a Block

Explode Block

Convert block instances back into individual editable objects

爆発する converts 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, 回転, and scale). The block definition remains in the library – only the selected instances are affected.

[__INSERT_IMAGE__]

Step-by-step

  1. 1Select one or more block instances on the canvas.
  2. 2クリック 爆発する in the Block Reference panel.
  3. 3The instances are replaced by individual geometry objects. All object properties (layers, 色) are preserved.
⚠️

注意: 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.

Block Instance Properties

Block Instance Properties

Adjust per-instance scale independently of the block definition

Context menu
Right-click → Properties

Each block instance has a configurable 規模 property that is independent of the block definition and other instances. Open the properties dialog by right-clicking a selected instance and choosing プロパティ.

プロパティ

財産 説明 デフォルト
規模 Uniform scale factor for this instance. 1.0 = 100%, 2.0 = 200%, 0.5 = 50%. 1.0

Dialog buttons

  • Update – Applies the new scale and closes the dialog.
  • セーブ – Applies the new scale and keeps the dialog open for further edits.
  • キャンセル – Closes the dialog without applying changes.
💡

ヒント: 押す 入る inside the properties dialog to apply and close, または ESC to cancel – no need to reach for the mouse.

ショートカット

Block commands do not have a default keyboard shortcut assigned, しかし Add Selected as Block action is available in the shortcut customization panel (Help → Shortcuts tab) and can be bound to any key combination.

アクション Default Shortcut ノート
Add Selected as Block None (customizable) Creates a block from the current selection. Disabled if no geometry is selected or block instances are selected.
Create Block Reference Right-click menu Available in the right-click context menu when geometry (not instances) 選択されています.
Edit Block Right-click menu Available in the right-click context menu when exactly one block instance is selected.
Exit placement mode / Edit mode ESC Cancels block instance placement without saving.

Supported Content

✔ Lines
✔ Arcs
✔ Circles
✔ Points
✔ Polylines
✔ Text labels
✔ Leader Text
✔ Multi-Leader Text
✔ Dimensions (線形, projected, 角度, 半径)
✔ Hatches
✔ Revision Clouds
✔ Gridlines / 軸

Not supported inside blocks: 画像, construction lines, tables, and nested block instances (blocks within blocks).

チップ & ノート

💡

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 – 例えば. the bottom-left corner of a detail, or the centre of a bolt pattern – to make insertion snapping predictable.

💡

Select All Instances: 使用 Select All Instances button to select every instance of a block at once – handy for bulk moves, layer changes, or exploding all copies together.

💡

Filter selection: 構造が非線形の振る舞いを示す場合、非線形または2次の静的解析が適しています フィルタの選択 ダイアログ, enable or disable the Blocks checkbox 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.
