Aia kekahiʻano'ē aʻe o ka mea composite e hiki iā mākou ke hana me Autocad. Eia nāʻaoʻao. Na wahi e hoopili wahi e, ma ke alanui, he pōpilikia physical waiwai e like me ke kikowaena o ka umekaumaha, no laila, i loko o kekahi manawa 'aelike, e hoʻohana i na mea kahi o polylines a me nā mea.

Hiki iāʻoe ke hana i kahi mea āpana'āina mai, e like paha, he polyline i paniʻia. Eia naʻe, hiki ke hanaʻia lākou mai ka hui pūʻana o polylines, laina, polygons a me nā kikowaena, i ka wā a lākou e pani nei i nā wahi pani i keʻano like.
