Measuring
Press M to activate the Measure tool, then drag from point A to point B. The distance (nm) appears:
- In the status bar (amber digits, right side).
- As a label at the drag midpoint on the canvas.
Switching to any other tool clears the measurement. No shape is ever created.
Pin a measurement. Press Enter after a measure drag to keep it as a persistent dimension — a labelled distance line that stays on the canvas, survives tab switches and autosave, and is never written to the .gds (it's a draw-only aid, like construction geometry). Pin as many as you like.
Measure an angle. Verify → Measure angle (3 clicks) arms a 3-click angle: click the vertex, then a point on each ray. The interior angle is drawn with an arc and a degree label, and pinned like a distance dimension. Esc cancels mid-collection.
The angle previews live as you go: click 1 drops a vertex dot, click 2 fixes ray 1 and rubber-bands ray 2 to your cursor with a running degree readout, and click 3 pins it. The reading you watch is the reading you get — it is computed exactly as the pinned dimension is.
Four measure modes. With the Measure tool active, the Properties panel shows a mode picker: Distance (drag), Angle (three clicks), Gap (two clicks on facing edges — the companion to a min-spacing violation), and Radius (arc centre, then a point on the arc). The mode stays until you change it, so you can take several of the same kind in a row. Below it is a list of every dimension pinned in the cell — click a row to jump to it, or delete it there.
Delete just one. With the Select tool, click a pinned dimension’s line (or either ray of an angle) to pick it — it turns white — then press Delete, or right-click and choose Delete dimension. Clicking anywhere else drops the pick.
A lasting record of a DRC run. Every design-rule check now also opens a report listing the violation count broken down by rule and layer, the cell and shape count checked, and whether paths were checked — so “how many, of what, where” survives the toast disappearing. Minimum-area limits are entered in µm², matching the width and spacing columns beside them.
Clear them all. Verify → Clear dimensions removes every dimension in the active cell in one undo step. (Distance and angle are the two modes today; radius, edge-gap, and area-box are planned.)
