Having used Inventor for a while

I can say it has its ups and downs, compared to CATIA V5.

Ups (positive remarks)

+ direct edit - useful feature sometimes when you're in a hurry and the model is a mess anyway

+ the "insert" command in assembly - where I use two coincidence commands in CATIA I get away with one "insert" command in Inventor.

+ rotating parts in assembly - that you can have parts move in sync is great

Downs (negative remarks)

- planes, points and whatever other geometry you might want to make use of for dimensioning a sketch has to be projected into the sketch first. This is hugely annoying when you're used to being able to dimension against planes and such

- direct edit - because it encourages users to be sloppy (which is something I will write more about at a later time)

- creating points and lines in 3D just isn't as easy, which is a pain if you're modelling something like, say, a spaceframe or a finned tube evaporator.

I'm sure many of you can come up with more positive and negative remarks about Inventor and some of you will disagree with me. I've used it only in my capacity as a teacher and I'm sure I'd come up with more if I was to use it where I have normally used Catia V5

When people think they know your job better...

An interesting situation. I made a statement about designers and designers. There IS a difference you know. There are designers who work with what the customer sees of the product and then there are designers who work with the inner workings of said product. One type is better described as an artist, the other as an engineer.

I've been a mechanical engineer for a long time, designing components for refrigerators and freezers. I've worked with artists to produce items that both look proper and function properly. I bloody well know the difference between an artist working with visual design and an engineer working with mechanical/functional design. And I described this difference with a few short sentences. One is concerned with what the customer sees/feels, the other is concerned with how it's made to work and how it's manufactured. And guess what? A teacher tells me that we shouldn't have preconceived ideas about different occupations! Well, it's not pre-conceived, it's a bloody fact. We have different specialists for different purposes, deal with it
