video tutorial

Is it anywhere good video tutorial? Where you guys know how to work with NVIL?

Hi Samardac!  I'll just quickly point you to the following Thread in which another forum poster recently asked the same question.  It is within a recently created "Tutorials" child board of these forums, but is the only thread there thus far.  Anyhow, your question is answered in more detail but the short answer is: tutorial resources are limited at the moment.  Be sure to read through the HELP contents within NVIL as that's your best place to start.  After you've got that figured out, come to the forums and perform a search for specific inquiries and have a read of what's already been discussed.  Failing that, feel free to ask.  There is an awareness that more information is needed, but I gather that the developer is very busy with developing NVIL (and a full-time job, etc.), and many of the more experienced users are busy using it for work, so there's a bit of shortage of resources in creating tutorials.  A user named Mason recently suggested the creation of a Wiki, so hopefully that's something that the community can build in time.  For now, read the HELP, and then get in there with both hands and dig around... at the risk of sounding obvious, making models is the best way to get to grips with NVil!
