Updating the A3 standard sheet 95
10 With the left viewport active, VPOINT R again and:
a) enter R R for the rotate option
b) enter 210 as the angle in the XY plane
c) enter 30 as the angle from the XY plane
11 We have set two viewpoints in this layout tab, one from above (the right viewport)
and one from below (the left viewport)
12 Right-click on Layout1 tab name and:
prompt Shortcut menu
respond pick Rename
prompt Rename Layout dialogue box
respond 1. alter name to MVLAY2
2. pick OK
13 Now have created two layout settings, MVLAY1 and MVLAY2 and the Model tab still
available.
A third layout tab display
Although we already have two layout tabs, we will create a third layout configuration
which is slightly different from the two ‘traditional’ layouts MVLAY1 and MVLAY2.
The sequence is long and uses co-ordinates for most of the entries. I would ask
the user to persevere with this exercise, as the end result is worth the time and
effort spent.
1 Still with the MVLAY2 tab, the right viewport active UCS BASE and layer VP
current
2 Left-click on the Layout2 tab and:
prompt Page Setup – Layout2 tab dialogue box
respond 1. Plot Device tab active and set:
a) Plotter configuration: None
2. Layout Settings tab active and set:
a) Paper size: ISO A3 (420.00 297.00 MM)
b) Drawing orientation: Landscape
c) Plot area: Layout
d) Plot scale: 1:1
e) pick OK
and Paper space entered with:
a) white drawing paper
b) dashed line plotting area
c) coloured rectangle – a new viewport
respond erase the viewport
3 Make layer SHEET current
4 Menu bar with Draw-Rectangle and:
prompt Specify first corner point and enter: 0,0 R
prompt Specify other corner point and enter: 405,257 R
5 Zoom-all and PAN to suit
6 Draw a line from: 0,15 to: @405,0 and customise the area below this line using
layer SHEET
7 Make layer VP current
96 Modelling with AutoCAD 2004
8 Menu bar with View-Viewports-Polygonal Viewport and:
prompt Specify start point and enter: 5,140 R
prompt Specify next point and enter: 140,140 R
prompt Specify next point and enter: 170,195 R
prompt Specify next point and enter: 170,250 R
prompt Specify next point and enter: 5,250 R
prompt Specify next point and enter: C R – the close option
9 A five sided viewport will be displayed at the top left corner of the drawing area
10 Menu bar with Modify-Mirror and:
prompt Select objects
respond pick any point on viewport border then right-click
prompt First point of mirror line and enter: 202.5,15 R
prompt Second point of mirror line and enter: 202.5,250 R
prompt Delete source objects and enter: N R
11 Repeat the menu bar with Modify-Mirror selection and:
prompt Select objects
respond pick any point on the two viewports then right-click
prompt First point of mirror line and enter: 0,136 R
prompt Second point of mirror line and enter: 405,136 R
prompt Delete source objects and enter: N R
12 We have now created four polygonal viewports
13 Menu bar with View-Viewports-Polygonal Viewport and:
prompt Specify start point and enter: 152.5,136 R
prompt Specify next point or [Arc/Length/Undo]
enter A R the arc option
prompt Enter arc boundary option
enter CE R – the centre point option
prompt Specify center point of arc and enter: 202.5,136 R
prompt Specify endpoint of arc and enter: 252.5,136 R
prompt Specify endpoint of arc and enter: 152.5,136 R
prompt Specify endpoint of arc and RETURN to end command
14 We have now added a circular viewport to our Layout3 display
15 Enter model space and make any of the new viewports active
16 Menu bar with View-Display-UCS Icon and ensure that On and Origin are both
active. I had to complete this sequence in all the five viewports.
17 In all viewports set UCSVP to 0
18 Make layer MODEL current and restore UCS BASE
19 Set five viewpoints to your own specification. I set the viewpoints to SE Isometric,
Left, Right, Front and Top, but it is your choice
20 Right-click on Layout2 tab and:
a) pick Rename from shortcut menu
b) enter MVLAY3 as the layout name
c) pick OK
21 At this stage the layout tab should display Model, MVLAY1, MVLAY2 and MVLAY3
similar to Fig. 12.1(b)
22 If you want the layout tabs to ‘be in order’ then right-click an MVLAY name and use
the Move/Copy option of the shortcut menu to position as required.
Updating the A3 standard sheet 97
Saving the layouts as a new standard sheet
1 Make any layout tab MVLAY1 (for example) current
2 Enter model space with the lower left viewport active
3 Layer MODEL and UCS BASE current

prompt Save Drawing As dialogue box
respond 1. scroll at Files of Type
2. pick AutoCAD Drawing Template File (*.dwt)
prompt list of existing template files in the AutoCAD template folder
respond 1. enter File name as: MV3DSTD
2. pick Save
prompt Template Description dialogue box

XX/YY/ZZ
2. Measurement: Metric
3. pick OK
5 Repeat step 4, but save as a template to your named folder with the same name, i.e.
MV3DSTD
6 Menu bar with File-Save As and:

respond 1. scroll and pick AutoCAD 2004 Drawing (*.dwg)
2. scroll and pick your named folder (MODR2004)
3. enter file name: MV3DSTD
4. pick Save
7 This saved template/drawing file will be used extensively when starting new model
exercises.
Checking the new MV3DSTD layout
Now that the MV3DSTD template file has been created we will add some 3D objects to
‘check’ the layout. Try and reason out the co-ordinate entries.
1 Close any existing drawings
2 Menu bar with File-New and:
prompt Create New Drawing dialogue box
respond 1. pick Use a Template
2. scroll and pick MV3DSTD.dwt – Fig. 12.2
