Hi, My name is Hebert Franco. I am Brazilian and I live in Vitória-ES-Brazil. First I ask for to excuses my bad English. Work with mockups and I practise a little of design. I have a machine CNC Router and one Laser Cut. Esteou starting to learn Rhinoceros and Grassrropper seems to be the perfect tool to make my imagination reality. I am entering in this forum to learn, to share experiences, to make friends and one will be possible, to pass a little of my practical experience. I finished to install Grasshoper. It seems a little difficult to use, but I know that she is necessary to study very, to read the totoriais, to follow the quarrels. The English certainly will be a barrier, but I am proto to make the possible one to learn. My first desire is to learn to make objects slice or ribs, as in the attached image. This part was made with much patience in sketchup and edited rabbets in corel draw one for one. Grasshoper certainly can make this very easy. Already I looked for tutorial on this, but not yet I found. If somebody will be able to help me with a tutorial one or commentary that helps to find this way, I am sincerely grateful.
