Viewer Guide

What the viewer reads, and how to get around a drawing.

Pan & Zoom

Drag to pan, scroll or pinch to zoom around the cursor. Keyboard: + and − zoom, F fits, arrow keys pan.

Measure

M · click · click

Turn on Measure, then click two points. It snaps to line ends, vertices and centres, and shows distance, ΔX, ΔY and angle.

Layers & Colours

ByLayer · ByBlock · ACI

Layers that are off or frozen in the file start hidden. Colour 7 shows white on dark backgrounds and black on white.

DWG Files

Save As → DXF

DWG is a closed format. Save as ASCII DXF from AutoCAD, BricsCAD or MicroStation, or use the free ODA File Converter.

Export

DXF → SVG · PNG

Save the visible layers as an SVG for the web or a PNG image for documents and email.

SVG Safety

scripts blocked

SVG files are shown as images, so any scripts or external links inside them never run.
