When you create a part, you first use the Create Part dialog box to define the properties of the part, and then you use the Sketch to sketch the two-dimensional profile of the base feature. You use the Create Part dialog box to define the following:
Name
Use the Name text field at the top of the Create Part dialog box to name the part you are creating. To rename a part, select Part
Rename from the main menu bar. For information on valid names, see “Using basic dialog box components,” Section 3.2.1.
After you create a part, ABAQUS/CAE displays the name of the new part in title bar of the current viewport.
Modeling Space
Use the Modeling Space radio buttons to choose the modeling space of the new part. You can define a part to be either three-dimensional, two-dimensional (planar), or axisymmetric. If you create an axisymmetric deformable part, you can toggle on Include twist in the Create Part dialog box to include a twist degree of freedom in your model. You can change the modeling space of a part after you have created it by clicking mouse button 3 on the part in the Model Tree and selecting Edit from the menu that appears. For more information, see “Choosing the modeling space of a new part,” Section 11.19.2.
Type
Use the Type radio buttons to choose the type of the new part. You can define a part to be either deformable, discrete rigid, or analytical rigid. You can change the type of a part after you have created it by clicking mouse button 3 on the part in the Model Tree and selecting Edit from the menu that appears. For more information, see “Choosing the type of a new part,” Section 11.19.3.
Base Feature
Use the Base Feature field to define the shape and the type of the new part's base feature. The shape and the type options that ABAQUS/CAE displays depend on the part's modeling space and type. You cannot change the type of a part's base feature after you create it. For more information, see “Choosing the base feature of a new part,” Section 11.19.4.
Approximate size
Use the approximate size text field to enter the size of the part. The size that you enter is used by ABAQUS/CAE to calculate the size of the Sketcher sheet and the spacing of its grid. For more information, see “Setting the approximate size of the new part,” Section 11.19.5. After you create the part and start sketching its profile, you can use the Sketch customization options to increase the sheet size. To display the Sketcher customization options click the 
tool at the bottom of the Sketcher toolbox.
