Use the dimension modification tool from the Sketcher toolbox to modify existing dimensions. You cannot modify the dimension that defines the radius of an arc.
To move and resize objects by modifying their dimensions:
From the modify tools in the Sketcher toolbox, select the dimension modification tool 
. For a diagram of the tools in the Sketcher toolbox, see “The Sketcher tools,” Section 19.4.1.
ABAQUS/CAE displays prompts in the prompt area to guide you through the procedure.
Select the dimension you want to change.
ABAQUS/CAE highlights the selected dimension. If you selected any type of dimension other than radial, ABAQUS/CAE also highlights all vertices in the viewport.
Select the appropriate vertices of the objects you want to move or resize.
Which vertices you select depends on what type of object you selected and whether you want to move or resize it.
Tip: In cases where you must select more than one vertex, hold down the [Shift] key as you click each handle. To select multiple vertices, you can also drag a rectangle around them. To unselect a vertex, use [Ctrl]+Click. When you are finished selecting vertices, click mouse button 2. For more information, see Chapter 6, “Selecting objects within the viewport.”
Use the text box in the prompt area to enter a new value for the dimension.
The object moves or resizes to accomodate the new dimension.
To move or resize more objects, repeat the above steps beginning with Step 2.
When you have finished moving and resizing objects, either
Click mouse button 2 anywhere in the ABAQUS/CAE window, or
Select any other tool in the Sketcher toolbox, or
Click the cancel button 
in the prompt area, or
Click the dimension modification tool in the Sketcher toolbox.
