Canvas & Selection

The canvas is the sheet. It is drawn at real paper size, so what you see is what the export produces. Zoom is only magnification, never a change to the drawing.

Navigation

Action	How
Zoom	Mouse wheel. The zoom centers on the pointer, so put the cursor where you want to end up.
Pan	Middle mouse button drag, from any tool. Or hold Space and drag with the left button.
Fit the sheet	VIEW ▸ Zoom Extents.
Zoom in / out by steps	VIEW ▸ Zoom In and Zoom Out.

The status bar shows the current zoom percentage and the cursor's position on the page.

Grid and Snap

Grid on the VIEW tab draws a reference grid; Snap makes drawing and dragging land on it. The grid size list offers 1, 5, 10, 25 and 50 page units. Neither affects the export; the grid is never drawn into output.

Selecting

The Select tool on the DRAW tab is the default mode; Esc from any other tool returns to it.

• Click an object to select it. The scene tree highlights the same item, and the property panel switches to the tab for that kind of object.
• Ctrl+Click adds or removes one object from the selection.
• Shift+Click in the scene tree extends a range; Shift also extends a marquee selection on the canvas.
• Click empty canvas to clear the selection (and leave path-edit mode).

Marquee selection

Dragging on empty canvas with the left button draws a selection window, following the CAD convention:

• Left to right draws a solid blue window. Only objects completely inside are selected.
• Right to left draws a dashed green crossing. Anything the box touches is selected.

Hold Shift while dragging to add the marquee result to the existing selection.

Moving Objects

Drag any selected object you created to move it. When several objects are selected, dragging one moves them all as a group, and the whole move is a single undo step. A click without movement on a member of a multi-selection collapses the selection down to that one object.

Objects that came from CAD are anchored to the sheet: styling applies to them, but they are not dragged around. Move geometry in the drawing and re-export.

Rotate and Scale Handles

A selected object you created shows an oriented frame with four corner handles for uniform scaling and a stemmed handle above it for rotation. Hold Shift while rotating to snap to 15° increments.

The frame adapts to what is selected:

• Images and symbols scale and rotate freely.
• Text scales its font size rather than stretching the letterforms.
• Shapes and merged paths transform their points about the center, uniform scale only, so arc segments stay valid.
• Circles resize by radius and have no rotation handle.
• Scale bars resize physically while keeping their meaning, because the drawing scale value adjusts so the bar still says something true.

Each drag is one undo step, and a click that moves nothing pushes no undo at all. For exact numbers, use the TRANSFORM ribbon tab: set an absolute rotation, rotate by an increment, turn 90° either way, or scale by a percentage.

Aligning

With several objects selected, the Align group on the VIEW tab aligns them left, center, right, top, middle or bottom, and distributes them evenly horizontally or vertically.

Editing Paths

Right-click a path you drew and choose Edit Path to enter path-edit mode: vertices become draggable handles, and the EDIT PATH ribbon tab appears for numeric editing. Arc segments show their center crosshair, radius lines, tangents and PI point while being edited, and dragging a shared vertex adjusts the neighboring arc so tangency is preserved. Esc leaves path-edit mode. See Drawing Tools.

Right-Click on the Canvas

Right-clicking an object gives the same operations as the scene tree's context menu (draw order, overrides, presets, materials, delete), plus Edit Path on a path. See Layers and Objects.
