Parametric Design and Automation Flashcards

In the Inventor Parameters dialog, what happens when you select the Export Parameter check box for a user parameter?

Answer: The parameter becomes a custom iProperty of the file

Exported parameters appear as custom iProperties, so they can be used in BOMs, parts lists, and title blocks.

Which unit should you assign to a user parameter that drives the instance count of a rectangular pattern?

Answer: ul

Pattern counts are unitless, so the parameter must use 'ul' to be accepted as a count value.

A sketch dimension displays the prefix 'fx:' in the graphics window. What does this indicate?

Answer: The dimension is controlled by a parameter or equation

The fx: prefix marks a dimension whose value comes from a parameter name or equation rather than a typed constant.

Where do reference parameters in the Parameters dialog come from?

Answer: Driven dimensions placed in sketches or features

Driven (reference) dimensions create reference parameters whose values can be read but not edited directly.

You want to remove model parameters that are no longer used by any feature or sketch. Which Parameters dialog option does this?

Answer: Purge Unused

Purge Unused deletes parameters that are not referenced by any geometry or equation.

Which equation correctly sets a width parameter to half of a parameter named Length plus 5 mm?

Answer: Length / 2 + 5 mm

Inventor equations reference parameters by name and use standard operators with optional units, without a leading equals sign.

What is the purpose of the Key check box in the Parameters dialog?

Answer: It flags important parameters so they can be filtered and used in iLogic forms and iPart tables

Key parameters can be filtered in the dialog and are prioritized when authoring tables and forms.
