Use the vertical construction line tool from the Sketcher toolbox to help position and align objects along a vertical line. Vertical construction lines are created parallel to the Y-axis of the Sketcher grid. Rotating the Sketcher grid does not affect existing vertical construction lines, but new vertical construction lines are aligned with the rotated grid. The following figure illustrates how a horizontal construction line and a set of vertical construction lines can be used to align circle centers. (Dashed lines indicate construction geometry.)
To sketch a vertical construction line:
From the construction tools in the Sketcher toolbox, select the vertical construction tool 
. For a diagram of the tools in the Sketcher toolbox, see “The Sketcher tools,” Section 20.4.1.
The vertical construction line moves horizontally as you move the cursor around the Sketcher sheet. Abaqus/CAE displays prompts in the prompt area to guide you through the procedure.
Click a point that will lie on the vertical construction line. Alternatively, you can type its X–Y coordinates in the text field that appears in the prompt area. (The Y-coordinate is arbitrary since it is ignored.)
To create additional vertical construction lines, repeat the previous step.
When you have finished creating vertical construction lines, do one of the following:
Click mouse button 2 anywhere in the Abaqus/CAE window.
Select any other tool in the Sketcher toolbox.
Click the cancel button 
in the prompt area.
