EXTRUDE

One of the most commonly used features, Boss-Extrude "Extrude" is a way of pulling a sketch profile straight out from a plane with a few optional considerations

• Start condition

• End condition

• Distance

• Contour

• Draft Angle (used primarily in mold-making)

Extrusions require at least one closed sketch region as part of the Parent Sketch

Insert→Boss/Base→Extrude

By default, this is your Sketch Plane but in some cases, you may not have a plane to easily sketch upon so this can be moved

For the purposes of this Introduction Course, nearly all features will begin on the Sketch Plane and no adjustments will be required here

• Simply enter the distance from the Start where you'd like the end of your extrusion to end

This is used when you want your feature to have Symmetry

This is super-useful because you'll have a Workplane through the center of your part which will come in handy later on when you're Patterning Features

• If you're unsure about your first Extrusion being Blind or Midplane, you can always switch later by Edit Feature, but beware that'd be changing the Space-Time-Continuum...

This requires Prior Geometry such that you can Extrude up to an Edge, Surface or Vertex

Select UpTo Surface/Vertex/Edge option and LMB the Entity you'd like in the BlueBox

This option is used if you need to Extrude beyond a certain point

Draft will continuously grow or shrink your profile at an angle against your Start Plane

Starting from the beginning surface of your Extrude, you may Extrude in the opposite direction with its own End Condition

NOTE: The Midplane Extrude eliminates this option as it is equivalent to Blind each distance divided by two

• For this introduction course, do not use this setting

• This setting will automatically be selected if there is a problem with your sketch

• If you have one Single Closed Loop, this will automatically be selected

• If you have Two Closed Loops, the space between the two will automatically be selected

• If you have three or more Closed Loops, nothing will be selected, you must select in the graphics area to choose what you'd like to be extruded

• Always use the Pink-Region for consistent results

  • You can click the outer profile, but all bets are off that it will work as intended

• RMB→Delete individual selected items to remove them from the Blue Box

• RMB→Clear All to remove all selections from the BlueBox

If you wanted to extrude in a direction not perpendicular to your sketch plane and had an entity you could click on (at some angle other than 90°) you may add that entity to the selection box

For the purposes of this Introduction Course, nearly all features will be extruded Perpendicular to their Parent Sketch

• Pull-drag the arrow with the LMB to guestimate how far you'd like to extrude

• Enter a Value before you're finished with the model

• If the feature has already been Extruded and the Parent Sketch Entity is NOT Fully Defined, you may also Pull-Drag that Feature
