Built something worth sharing? Draw it in Hamina, select every zone that belongs to it, copy, and paste the result below. The form works out the geometry for itself — it only needs you to say what the thing is and which way it faces.

Select and copy

In Hamina, select all the zones making up your object and press Ctrl+C. Do not include walls or access points.

Paste and describe

Paste it below, add a name and a line about what it models, and check the preview looks right.

Send

Copy the submission block and email it over. Your name stays on the object in the library.

Paste straight from Hamina. Coordinates can be anywhere on your floor plan — the object gets re-centred on the origin automatically.

Pick the main one. If it belongs in several, say so in the description and it will be tagged for all of them.

Comma separated. These feed the search box.

Every object in the library faces the same way, so they line up when pasted together.

Your LinkedIn profile or personal site. If you give one, your name becomes a link on every object you contribute. Leave it empty if you would rather only your name showed.

Contributor terms Version 1.0

  1. It is your own work. You drew it yourself. It is not traced, converted or derived from a manufacturer’s CAD, BIM or product model, and not copied from another object library.
  2. You licence it under CC BY 4.0. Worldwide, free of charge and irrevocably, so that anyone may use, adapt and redistribute it — commercially included — provided they credit the source. You keep the copyright; you are granting a licence, not signing it away.
  3. It will be modified. Every submission is re-centred on the origin, rotated to a common orientation, rewound and rounded before publication. It may also be renamed, recategorised, corrected, or extended for consistency with the rest of the library.
  4. It may be declined or withdrawn. Not everything gets published, and anything published can be taken down later, without explanation.
  5. Your name is published alongside it, together with the link you give if you give one. That is the only personal information kept, and publishing it is the point rather than a side effect. Ask and your name will be removed from the listing — but the object itself stays published, because the licence in point 2 cannot be revoked once granted.
  6. No warranty. Attenuation figures are estimates, not measurements. Anyone relying on them for a design validates them against their own survey. Neither you nor this site is liable for what someone builds on them.
