Troubleshooting

• "Would create a cyclic reference" — you tried to place an instance that would eventually contain itself. Restructure: flatten one branch, or place the array inside a different cell.
• Nothing draws when I click — the active layer may be hidden or locked, or you're inside a cell you did not mean to be in (check the breadcrumb).
• Ctrl + 0 jumps to a tiny corner — you have something selected far from the main content. Press Escape first to clear selection, then fit.
• Paste lands far from the cursor — Paste uses the cursor's world position as the anchor. Move the cursor into the canvas before pressing Ctrl + V.
• A shape I drew isn't in the exported .gds — it's probably flagged "For construction" (dotted outline). Toggle the flag off in the Properties panel. Bitmaps are also intentionally excluded — trace them first (§11).
• My colleague's other tool doesn't show my font — Glyph embeds the font inside the .gds (a private __GLYPH_FONTS__ cell) and reads it back when Glyph re-opens the file, but tools like KLayout / Clewin ignore that cell and render nothing for the text. Flatten the text first (§12) so the glyphs become real polygons that every tool draws.
• The Claude pill won't go green — the MCP server probably isn't running. Click the pill → "First time? Open setup guide" and run the installer; the pill turns green automatically once the server is up and the token matches.
