I'm trying to learn Autocad.

Anyone know any good online tutorials?

One thing I can't work out is why my imported drawing has some lines in green and some in red.

what does it all mean?

Cheers

Chris

The different colours usually represent different layers.

In interior design you tend to have a drawing for flooring, decoration, electrical works, mechanical works, ceilings etc.

In olden days, when I started, each drawing was done on a seperate sheet of tracing paper. Now you draw on the building fabric (i.e. the structural bits) on one layer, then the flooring on another layer, the ceiling on another layer etc etc. Idea is you can turn layers on and off so you just look at the bit you are interested in. Also should highlight conflicts better, i.e. air-conditioning cassette can't go in the same bit of ceiling as a light fitting.

When I left interior design, everyone had drawing boards, pens and set squares. When I came back everyone had mice and TV's on their desks.

I took a course at my local college, was free and in the evenings and now it's dead easy.

Can you merge layers like you can on photoshop?

you can move a objects to any layer,

if you think as layer as a piece of blank tracing paper, you can move onjects on to any layer, add layers, turn off layers, rename layers.

Colours are used to make drawings more readable and also most plotters use colours as a way of line thickness so if the line was red it would plot out thick, if green it could be thin.

if you are stuck you can also u2u me, 20 years using Autocad
