Using Constraints When Sketching
You can use constraints while you are sketching by pressing Shift as you draw. Shift constraints works as
follows:
Constrains straight lines and radii of polygons to horizontal or vertical lines.
Limits the chords of 3-point arcs, the radii of arcs from center and end points, and the axis of ellipses to
multiples of 45 degrees.
Limits 2-point and 3-point arcs to 90, 180, or 270 degrees.

Sketching a Line

1 Select a tool that allows for a line, for example, click Home tab
2 Click Place Lines tab (or respective Place <Element> tab or Create <Element> tab)
3 On the Options Bar:
to
offset the placement of a sketch line by the value you specify.
When you use offset with the Pick Lines option, the element or sketch line is offset
from a line specific to an element (for example, the location line in a wall). The new
element has the same shape and length as the picked line.
If you use offset when you draw a sketch, the element or sketch is offset from the
cursor location. You can create an element of any length or shape when draw a sketch
with an offset.
You can also specify the offset location line for walls by selecting an option from the
Location Line drop-down.
NOTE If you draw with the chain option turned on, the newly created lines are also
chained. Therefore, you can create a shape similar to an existing shape by tracing it
with an offset.
preset a value for the radius. This option is available for walls or lines when you draw
a rectangle, circle, arc, or polygon.
Use a radius to:
specify a fixed radius for a circle, a circle in which a polygon is inscribed (or around
which it is circumscribed), an arc from center and endpoint, or a tangent arc. The
preset radius puts constraints on the element or sketch so that fewer clicks are re-
quired to complete it. With a preset radius, you can create a circle with one click
or a fillet with 2 clicks.
specify a rounding of corners (the radius of the fillet) when joining lines (with or
without the chain option), when you draw a rectangle, or when you fillet using
the Fillet Arc sketch option.
panel (Line).
a Optionally, select Offset and specify a value.
b Optionally, select Radius and specify a value.
A radius creates fillets at the specified radius between line segments, allowing you to create
a rounded chain of lines. A line must be joined to the end of another line for a fillet to
display. If a line is connected to more than one line, a fillet cannot be created.
