In a Top-down assembly, you create In-Context features. An In-Context feature is a

feature that references geometry from another component. The In-Context feature has an

External reference to that component. If you change geometry on the referenced

component, the associated In-Context feature also changes.

An In-Context feature is indicated in the FeatureManager with the ''>'' symbol. The

External references exist with the feature, Sketch plane or sketch geometry. The update

path to the referenced component is contained in the assembly. When the update path is

not valid or the referenced component is not found the ''?'' symbol is displayed in the

F eatureManager.

In the BOX assembly, develop InPlace Mates for the MOTHERBOARD,

POWERSUPPL Y and CABINET components.

Create External references with the Convert Entities Sketch tool and extracting geometry

from the sketch of the BOX assembly.

Working with In-Context features requires practice and time. Planning and selecting the

correct reference and understanding how to incorporate changes are important. Explore

various techniques using InPlace mates and External references developed In-Context of

another component.

Assembly Modelina Techniaues with lnPlace Mates:

Plan the Top-down assembly method. Start from a sketch or with a component in the assembly.

Prepare the references. Utilize descriptive feature names for referenced features and sketches.

Utilize lnPlace Mates sparingly. Load all related components into memory to propagate changes.

Do not use lnPlace Mates for purchased parts or hardware.

Group references. Select references from one component at a time.

Ask questions. Will the part be used again in a different assembly? If the answer is yes, do not use

lnPlace Mates. If the answer is no, use lnPlace Mates.

Will the part be used in physical dynamics or multiple configurations? If the answer is yes, do not use

lnPlace mates.

Work in the Edit Component tool to obtain the required External references in the assembly. Create

all non-referenced features in the part, not in the assembly.

Obtain knowledge of your company's policy on lnPlace mates or develop one as part of an

enoineerinq standard.
