Hi, Have you just completed a disappointing Alias course at Uni? Can’t get an entry level job because you don’t know enough about Alias Class A Modelling and Reverse Engineering. This is normal because universities can’t afford to employ top Alias Automotive modellers. Please don’t worry, you’ve found the right website. If you need PROFESSIONAL online Alias Automotive and Reverse Engineering video training + regular help and reviews to Industry Entry level ( A Class Principles), please register on my website for free and I will send you the course details: I have a 100% success rate at finding an Alias position with students who complete the course.

Here’s a student question that I have answered and would like to share with all you aspiring Alias Automotive guys


Q) “Hi Graham
I want to build a door mirror for the first time. Do you have a tutorial please and what tips would you give to a Mirror Rookie?
I thank you kindly for your time

I would give a door mirror task to a guy with several years experience,

as mirrors have to be modeled on discrete axes and not in the world space default  planes. They are often complex in form with a lot of tricky details and generally there is a requirement towards the end of the project for full G3. Taking this into account it is best to start on a mirror which has been designed to be a little less challenging than the A5 mirror.

Modeling icon Barry Kimball says that at times he spends 30% of his hours on a complete exterior just building the door mirror.


This is not something that you can rush into and is not something that you can expect to get good highlights on the first hit.

Learning to build a mirror is a journey and you should be prepared to have 2 or three goes at your first one (G2 only) and then move on to the next level of design complexity. So building a mirror, is a mini Alias journey, in it’s self. It is one of the areas where you will really start to learn about achieving G3 by *accelerating the edges of Parents and also learn where you need to trim or extend to (parent boundaries/chordal width of fillets) in order to be poises to create G3 highlight flows. (*My students learn to reposition the CV hulls which determine G3 crvtr. condition. They learn the first principals of direct modeling the CV hulls and what follows takes several years of experience.)


So it’s not easy and you shouldn’t expect smooth flowing HL’s, until you have spent a few weeks in the amazingly consuming world of mirrors and unless you have several years experience, you won’t be able to meet G3 criteria for all the transitions. It is also important to remember that in a studio you would be given mesh-data to work from taken from a scan of the clay or hard model.

The best place to start is with my simplified door mirror tutorial:
  • build your first mirror to G2 and then study what would be required to accelerate the parent surfaces into the transitions
  • create the body of the mirror with your focus on good HL’s and EVEN CV disribution.
  • think about where to join your patches on the mirror body, so that you can create small trans. srfs. Here you have to start planning patch-layout.
  • when you start the trans srfs, don’t be afraid to change the size and number of parent srfs of the mirror body (patch-layout), using Extend.
  • always be prepared to scrap the first attempt, if you realize a better methodology along the way. Learn by your mistakes and don’t plough more time into something if the structure of the mirror body is basically flawed (uneven CV distrib/jagged zebra plot et cetera)
Once you can build a door mirror which has at least some of the transitions conforming to  G3 criteria, you have reached a new level within Alias.
Finally and to reiterate don’t rush to get G3. Build a G2 version first. That is hard enough, believe me!

kind regards
