The modification of 3D models - Introduction to AutoCAD 2011: 2D and 3D Design - page 272

Fig. 14.4 First example - inserting 3D blocks
N o t e s
1. It does not matter in which of the four viewports any one of the
blocks is dragged and dropped into. The part automatically assumes
the view of the viewport.
2. If a block destined for layer 0 is dragged and dropped into the layer
Centre (which in our acadiso.dwt is of colour red and of linetype
CENTER2 ), the block will take on the colour (red) and linetype of
that layer ( CENTER2 ).
3. In this example, the blocks are 3D models and there is no need to
use the Explode tool option.
4. The examples of a Four: Equal viewports screen shown in Figs 14.3
and 14.4 are in fi rst angle. The front view is top right; the end view
is top left; the plan is bottom right.
Second example - a library of fastenings ( Fig. 14.6 )
1. Construct 3D models of a number of engineering fastenings. In this
example only fi ve have been constructed - a 10 mm round head rivet, a
20 mm countersunk head rivet, a cheese head bolt, a countersunk head
