Step 5 Now add the other vertical and horizontal dimensions in the same manner. Don't
worry if the dimensioning defaults are different on your system.

Select arc or circle: (pick 1)

Specify dimension line location or

[Mtext/Text/Angle] : (pick 2)

Select arc or circle: (pick 3)

Specify dimension line location or

[Mtext/(Text/Angle]: (pick 4)

lfthe radii do not respond in the way that you want,
sure you are working in the correct dimension style,
then use Modify to change the parameters. The lines
of the radius dimension are under the Fit tab.

Step 7 Your dimensions are fine, so now add center marks. From
either the pull-down menu or the toolbar, choose Center
Mark.

Command:CENTER

Select arc or circle: (pick the radii) +

+

The lines associated with the center mark are determined
under the Lines tab.

Step 8 The dimensions added are associative dimensions. This means that the dimensions are
entered relative to the points that you have identified. These are called defpoints, and
there is a special layer created for them under your Layer menu. This layer does not
plot, so be careful not to make it current.

This means that you can STRETCH the part and
the dimensions will automatically update.

Command: STRETCH

Select objects to stretch by

window ...

Select objects:C
First corner: (pick 1)

Other corner: (pick 2)

Select objects:.J

Base point: (pick 3)

New point:@1<90 (or pick 4)

The resulting object should look like this.

Your objects should stretch and the vertical di-
mension should change. If only the dimensions
stretch and not the part itself, it is because the Ob-
jects layer, or whatever layer you have placed the
objects on, is locked. Under the Layer toolbar,
unlock the Objects layer.

Step 9 Finally, if you have entered all the dimensions and then find that they are the wrong
scale or the wrong units, that the arrowheads should be ticks, or some other problem,
you can edit the dimensions singly or in groups by changing the options in the
Dimension Style dialog box. What if the dimensions should really be in fractional
rather than decimal? You can change the dimension style and apply it to the current
drawing.

First, save the drawing under a different name by using the 'Save as' function under
the File pull-down menu. Now you have two copies, one with fractions and one with
decimals.

The next step is to make a new dimension style that incorporates the necessary
changes. Access the Dimension Style dialog box.

From the main dialog box, pick New and create a style called Fractional using Me-
chanical as the base.

Once this is entered, pick Continue and go to the Primary Units tab to change the units
to fractions. Pick OK and you will return to the Dimension Style Manager.

Use the Set Current button to set the current style to Fractional and close the dialog
box.

Command:DIM
Dim:UPD
Select objects: (pick all the

objects with crossing or window)
Select objects:..J

Make a dimension anywhere on the screen. Pick
the Matchproperties icon. Pick the new dimen-
sion, then all the other dimensions. They will up-
date.

To use update, change the mode to dimensioning
mode, then use UPD.

To update all of your dimensions to fractional, use Matchproperties or the UPDate
command.
