OUTCOMES OF WORKSHOPS:

These Workshops are designed tobeasimpleintroductiontoAutocad 2011, with the eventual outputbeingaverysimplegarden design similar to the one opposite (Image 1).

Theideaistogetyoufamiliarwith the basic tools and workings of what is a useful but complex programme.

The design opposite is a simple garden design drawn in Autocad,andbyfollowingtheseWorkshopsyouwillbeabletocreate something similar, with each one building towards the finisheddesign.ItisthereforeadvisedthatyoufollowtheseWorkshops in sequence to get the most from them.

HOW TO OPEN A NEW AUTOCAD DRAWING: DoubleclickontheAutocadicononyourcomputer Closethe“WelcomeScreen”ifoneappears,andyoushould be faced with a screen similar to Image 2 on the right. This is thestandard2011workspacesetup.However,itdoesnotaccuratelyreflectthesetupofpreviousversionsofAutocadwhicharestillusedinlandscapeofficesandwhichyoumaywellencounterintheworkplace.Forthisreason,weneedtochangethelayoutbygoingto: 2DDraftingandAnnotation>AutocadClassic(asinImage3)

This will setup the screen in the classic Autocad workspace from whichyoucanstartworking(seenextpage).
