Question

1. In Creo Parametric, which command can we use to adjust the tapered angle of a surface?

2. Will dimensions be updated when the geometry is modified?

5. What is the main difference between straight and sketched holes?

6. What is the difference between coaxial and radii holes?

*All questions are refered to creo**

Answer 1

1. Using extrusion tool, while extruding as solid or surface, there will be a checkbox with the name "Add taper". This command adds draft to surface, range -89.9 to 89.9.

or

Open Model tab >> draft >>References >> Draft surfaces(Select surface to taper or draft) >> give angles

Draft command

2. Yes, If dimensions are not locked then modifying geometry leads to an automatic update of dimensions.

5. Straight hole uses the predefined geometry by the system, creates a one-sided simple hole by default. Two-sided simple straight holes can be created using Shape tab. Consists of extruded or revolve cuts and not of any industry standards. Do not require any sketch.

Sketched holes need sketched profile. You cannot create two sided sketched holes.

6. To create or locate coaxial holes one linear and axial reference is necessary. Can be used with the reference surface, plane or axis. Offset placement reference wont be available with this holes.

Radial holes need linear and angular dimension to locate or create hole. Can be used with cylindrical, conical solids, reference planes. Radial cylindrical holes for cylinders and cones, radial axial holes for planes.

Diameter hoels Rotate the hole around a diameter reference. Need axis along with the two dimensions used in radial holes. Can be used with reference a planar solid surface or a datum plane.
