This topic will explain where to find the Gear function, and explainthe options found in it.This topic will also give a brief descriptionof Dynamic Drawing, the Snap Increment function, explain Gear creationwith quick steps, and provide links to related topics.

The Gear Function

The Gear function creates a gear based on the settings that you definein the Data Entry Manager.

Dynamic Drawing

This function supports Dynamic Drawing which allows you to use a combination of sketching and data entry to create the entities. After initially sketching the entity, it becomes an active entity, which is an entity that is in Modify Mode. Entities in Modify Mode display in the current Entity color, but displays with a greater line thickness to make them easier to identify. Active entities can be modified using data entry. The benefit of Dynamic Drawing is that you can quickly sketch a point to get the approximate result and then use data entry to update to the exact dimensions, and coordinate values as needed.


Entities in Modify Mode

Final Entities


In the images above, we see entities which are still in Modify Mode, followed by those same entities after they are finalized.

Snap Increment

This function support the use of the snap increment when selecting the location of the entities. The snap increment allows you to get precise results when using mouse selection and helps to reduce data entry modifications.

To open Gear:

  • In the Shapes group, of the Create 2D ribbon,click the down arrow under Gear and click Gear.

The parameters display in the Data Entry Manager.

The Data Entry Parameters


  • Number of Teeth - setsthe number of teeth on the gear.
  • Pressure Angle (1)- sets the angle of the gear teeth.

  • Pitch(4) - setsthe pitch of the gear.

  • Outside Diameter(3) -sets the greatest diameter of the gear.

  • Root Diameter(6) - setsthe inside diameter ofthe gear.

  • Root Fillet Radius(5) - setsthe radius formed between the individual teeth and the RootDiameter.

  • Tooth Corner Radius(2) - setsthe radius formed at the end of the gear tooth.
  • Tolerance - allows the user to adjust the tolerance used for gear creation without the need to change the overall CAD tolerance.


  • X- is the X-axis location of the ellipse origin.

  • Y- is the Y-axis location of the ellipse origin.

  • Z- is the Z-axis location of the ellipse origin.

  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps - Gear

  1. Set the Parameters to set the definition of the gear.

  2. Set the Origin of the gear.

  3. Click OK to create the gear.

  4. Click Cancel to exit the function.
