ACP Parametric Design and Automation 2 — Questions and Answers
Question 1: In the Inventor Parameters dialog, what happens when you select the Export Parameter check box for a user parameter?
- The parameter is converted to a reference parameter
- The parameter is written to a linked Excel spreadsheet
- The parameter becomes a custom iProperty of the file (Correct answer)
- The parameter is copied to all open documents
Correct 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.
Question 2: Which unit should you assign to a user parameter that drives the instance count of a rectangular pattern?
- ul (Correct answer)
- deg
- in
- mm
Correct answer: ul
Pattern counts are unitless, so the parameter must use 'ul' to be accepted as a count value.
Question 3: A sketch dimension displays the prefix 'fx:' in the graphics window. What does this indicate?
- The dimension is controlled by a parameter or equation (Correct answer)
- The dimension is a driven (reference) dimension
- The dimension is linked to a drawing view
- The dimension has a tolerance applied
Correct 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.
Question 4: Where do reference parameters in the Parameters dialog come from?
- Parameters derived from a base component
- Parameters created with the Add Numeric button
- Driven dimensions placed in sketches or features (Correct answer)
- Parameters imported from an Excel file
Correct answer: Driven dimensions placed in sketches or features
Driven (reference) dimensions create reference parameters whose values can be read but not edited directly.
Question 5: You want to remove model parameters that are no longer used by any feature or sketch. Which Parameters dialog option does this?
- Link
- Reset Tolerance
- Purge Unused (Correct answer)
- Filter: Key
Correct answer: Purge Unused
Purge Unused deletes parameters that are not referenced by any geometry or equation.
Question 6: Which equation correctly sets a width parameter to half of a parameter named Length plus 5 mm?
- Length:2 + 5mm
- [Length]/2+5 mm
- Length / 2 + 5 mm (Correct answer)
- =Length/2+5
Correct answer: Length / 2 + 5 mm
Inventor equations reference parameters by name and use standard operators with optional units, without a leading equals sign.
Question 7: What is the purpose of the Key check box in the Parameters dialog?
- It flags important parameters so they can be filtered and used in iLogic forms and iPart tables (Correct answer)
- It converts the parameter into a multi-value list
- It makes the parameter visible in all assemblies
- It locks the parameter against editing
Correct 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.
