C’est pas hyper technique mais est-ce que vous connaissez un logiciel (ou un site) pour dessiner le plan d’un appartement facilement ?
Un crayon et du papier + une photo/scan avec le smartphone? Tu pouuras même annoter le plan, sans changer de crayon, pour le rendre encore plus informatif ;)
It looks quite clever. As a pencil user, I would gladly try a few of those if they were manufactured.
But this is not correct:
For the casing, a lot pencils, most noticeably cheap ones, do not use wood for casing. It’s recycled plastic or some stuff like that. Here in France, I think Bic is recycling plastic to create the casing of their low cost pencils and colored pencils, while making it look somewhat like wood. I would say Staedtler does it too for its real entry level pencils but I’m not sure.
Like paper, pencil is one of those innovations that has reached maturity (to not say ‘perfection’) but it doesn’t mean there is not much research still going on. Exactly like with paper ;)
