The Fixture
step creates a fixture based on existing features: the intersection
of 2 lines, a line segment joining 2 points, or a specified
position and angle. The step can also be used to add an offset
position or angle to an existing fixture.
Creating a
fixture
To create a fixture, perform the following steps.
Select a Definition mode that allows
you to create a new fixture: PointAndAngle, TwoPoints, or TwoLines, depending on what
features you want to make your fixture from.
Create a fixture by drawing in the specified image or by linking
the appropriate feature inputs. Because the Fixture step creates
fixtures from existing objects, by default it displays the
annotations of previous steps. The easiest way to link position
values from existing features is to drag and drop directly from
Quick Watch flyout panel.
Select a SourceFixture. This will be
the parent fixture of the coordinates used to define a new
fixture.
Optionally, set an offset. For details, see below.
Offsetting a
fixture
A fixture offset can be applied to a new or existing
fixture.
Select OffsetExistingFixture as a
DefinitionMode
to offset an existing fixture, or add an offset to a new fixture by
setting the Fixture
offset: Enable input to True. You can also add a fixture offset
by clicking the Add
fixture offset () toolbar button in the
Project toolbar.
If offsetting an existing fixture, the Source fixture indicates the
fixture you are modifying.
Define the offset: the easiest way to set the offset is to click
Set offset in
the
Configuration pane, or click the Add fixture offset toolbar
button, and draw it on the image itself. When drawing the offset, a
yellow rubberband indicates which fixture you are offsetting. Click
at the new origin, and drag out in the direction of the X-axis,
then click to finish.
Alternatively, you can specify a change in position and an
offset angle relative to the source fixture, explicitly using the
edit boxes.
If you want to clear the fixture offset you have drawn, click
the Clear fixture
offset () toolbar button.
