Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Models now stand upright. 3MF, Rhino (3DM) and DXF files made with Z as the up direction — the usual choice in CAD software — no longer appear lying on their side. • New setting for STEP, IGES and AMF files, which don't record which way is up: choose Z up (the default) or Y up in the CAD QuickLook app. • 2D DXF drawings now preview: lines, arcs, circles, polylines, splines, blocks, dimensions, text and hatch fills, shown flat from above, with pan and zoom. • A drawing with nothing to show now says so instead of showing only the file icon. • Sturdier handling of damaged or unusual DXF files.
