How do splines help in achieving the sleek design of cars?

Rearrange these steps in the correct order to draw a spline:

• Press “Enter” to end or “C” to close the polyline.

• Specify the first point of the spline.

• Specify the next point(s).

• Type "SP" or select the "Spline Button"

Match the MODIFIER with its description:

• Close “C”

• Specifies the distance by which the spline is allowed to deviate from the specified fit points.

• Method “M”

• Specifies the knot parameterization.

• Tolerance “T”

• Closes the spline by defining the last point to be coincident with the first.

• Knots “K”

• Controls whether the spline is created with fit points or with control vertices.

Which term refers to the direction and magnitude of a spline's curve at its start and end points?

• Tangency

• Control Points

• Degree

• Knots

Match the case study with its description:

• The Jaguar E-Type Sports Car

• Spline-based techniques allow for seamless parkour and climbing.

• The Guggenheim Museum in Bilbao

• Elegant curves studied using splines set it apart as a design icon car.

• "Assassin's Creed" Game Series

• Splines in CAD translated a visionary design into a structurally sound masterpiece.

Match the common misconception or query with its solution:

• Want to adjust a previously drawn spline

• Restart the polyline command and use "close" or connect to the last point manually.

• Made an error

• Control points shape the curve; fit points are where the spline touches.

• Confused about control vs. fit points

• Use the "grips" or "PEDIT" command.

• Accidentally pressed escape

• Press "CTRL+Z" or use the "UNDO" command.

Type "__" as a shortcut key to create a spline in AutoCAD.
