Sketch-Based Features in catia

Features are entities you combine to make up your part. The features presented here are obtained by applying commands on initial profiles created in the Sketcher workbench (See Sketcher User’s Guide) or in the Generative Shape Design workbench (See Generative Shape Design User’s Guide) as well as surfaces.Some operations consist in adding material, others in removing material. In this section, you will learn how to create the following features:

Create a Pad: Click this icon, select the profile to be extruded and enter the parameters you need in the dialog box.
Using the Sub-elements of a Sketch: right-click the Selection field from the Pad or Pocket dialog box and select Go to Profile Definition to display the Profile Definition dialog box.
Create an ‘Up to Next’ Pad: Click this icon, select the profile to be extruded, set the Type option to Up to next and enter the parameters you need in the dialog box.
Create an ‘Up to Last’ Pad: Click this icon, select the profile to be extruded, set the Type option to Up to last and enter the parameters you need in the dialog box.

Create an ‘Up to Surface’ Pad: Click this icon, select the profile to be extruded, enter the parameters you need, set the Type option to Up to surface in the dialog box and select the required surface.
Create a Pad from a Surface: Click this icon, select the surface to be extruded and enter the parameters you need.
Create a Pad not Normal to Sketch Plane: Click this icon, select the profile to be extruded, expand the dialog box, enter the required parameters, define a new reference for the extrusion direction.
Create a Multi-Pad: Click this icon, select the sketch to be extruded and specify a length value for each domain.
Create a Drafted Filleted Pad: Click this icon, select the profile to be extruded and enter the parameters you need in the dialog box.
Create a Pocket: Click this icon, select the profile and enter the parameters you need in the dialog box.
Create a Pocket from a Surface: Click this icon, select the surface to be extruded and enter the parameters you need.
Create a Multi-Pocket: Click this icon, select the sketch to be extruded and specify a length value for each domain.
Create a Drafted Filleted Pocket: Click this icon, select the profile to be extruded and enter the parameters you need in the dialog box.
Create a Thin Solid: Click one of these icons, check the Thick option and enter values to define the thickness.
Create a Shaft: Click this icon, select the profile to be revolved about the axis and enter angle values.
Create a Groove: Click this icon, select the profile to be revolved about the axis and enter angle values.
Create a Hole: Click this icon, select the face to locate the hole to be created and enter the required parameters in the dialog box.
Create a Hole on a Non-planar Face: select a non-planar face and a point on that face, then click this icon and enter the required parameters in the Hole Definition dialog box.Locating Holes: To constrain the location of the hole, multi-select two edges of the face on which you wish to position the hole, then that face.
Create a Threaded Hole: Click this icon, select the face to locate the hole, define the hole shape, check Threaded, click Specifications and enter the required values in the Thread dialog box..
Create a Rib: Click this icon, select the profile to be swept along a center curve, select this center curve and set the position option in the dialog box.Trimming Ribs or Slots: If the rib or the slot cannot be trimmed by existing material, the only way of obtaining a rib is by using the Thick Profile option.
Create a Slot: Click this icon, select the profile to be swept along a center curve, select this center curve and set the position option in the dialog box.
Create a Stiffener: Click this icon, select the profile to be extruded, and specify whether this extrusion is to be done in two or three directions.
Create a Multi-sections Solid: Click this icon, select the section curves, the guide curves and if necessary the spine of your choice.
Remove a Multi-sections Solid: Click this icon, select the section curves, the guide curves, the closing points and if necessary the spine of your choice.
Create a Solid Combine: Click this icon, select the components which intersections you want to compute.

How Sketches are Located in the Specification Tree

Up to Part Design Version 5 release 14 the sketches used for creating sketch-based features were located directly below the features in the specification tree. Now, to improve the visibility of your design process this behavior has changed: new rules define the location of sketch entities in the specification tree. The How Sketches are Located in the Specification Tree section covers this new behavior.
