Figure 17.1 Multishape extrusion
As you are working in sketch mode, you can define the properties of the
extrusion prior to completing the sketch. Your sketch will define the shape
of the extrusion, but you also need to determine the distance of the third
dimension for your solid geometry. The Depth setting on the Options Bar
allows you to set the distance for the extrusion. Alternatively, you can use
the Extrusion End and Extrusion Start parameters visible in the Properties
palette while sketching, keeping in mind that these both reference the
workplane of the extrusion. These values can be changed after the sketch
is completed and the extrusion is made, but it is helpful to know the value
prior to completing the sketch. The default value is 1′-0″ (300 mm), but if
you change it, the value that you input will be used for the next extrusion,
until you exit the Family Editor.
When you have completed the sketch for an extrusion, you must click the
greencheckmarkbuttonontheModepanelofthecontextualtabinorderto
exit sketch mode and return to the Family Editor. If you want to cancel the
creation of the extrusion, you can click the red X button on the Mode tab.
If, during the process of sketching, you change the ribbon while in sketch
mode, the contextual ribbon tab may disappear from view, which can lead
to some confusion at first because the FinishEdit Mode button is not visible.
Just remember (and this applies in all instances) that the active tab of the
ribbon is always highlighted, so take a look back at the ribbon and simply
select the correct tab.
You can edit the shape of an extrusion by clicking it and dragging the
grips that appear at each shape handle of the solid geometry. This includes
changing the depth of the extrusion, which can be done by editing it in a
view perpendicular to the view in which the extrusion was sketched. Using
