Use the commands on this dialog to draw 2D shapes in the model.
Press BACKSPACE to undo you last action.
Navigate Backwards
Returns you to the command that activated the sketching commands. Unless you click
Accept 
, any sketches or edits to sketches that you have made are discarded.
Draw
Select one of the Draw commands to draw in the model.
Line
Draws a single line or a series of connected lines. When you draw a series of lines, the second point of one line is the first point of the next line. Select the Line command again to exit draw line.
Circle
Draws a circle using a center point and the radius.
Ellipse
Draws an ellipse using the center point and two edge points. The center point and the next point define half the length of the major axis and the rotation angle. The last point defines half the length of the minor axis.
Arc
Draws an arc using three points. The first two points define the arc ends. The third point defines a point on the arc.
Rectangle
Draws a rectangle using three points. The first two points define the width and rotation angle of the rectangle. The third point defines the height.
Fillet Rectangle
Draws a fillet rectangle using four points. The first two points define the width and rotation angle of the rectangle. The third point defines the height. The fourth point defines the fillet radius.
Fillet
Creates a rounded corner, or fillet, between two elements using a radius you specify.
Dimensions
Distance Between
Constrains two elements to a specified distance apart. If you move one element, the second element moves to maintain the specified distance.
Angle
Constrains two elements to a specified angle between them.
Radius
Constrains the radius of an element to a distance that you specify.
Relationships
Parallel
Makes two lines parallel.
Perpendicular
Makes two elements perpendicular. You can make two lines, a line and an arc, or a line and a circle perpendicular.
Concentric
Makes an arc or circle concentric with another arc or circle.
Tangent
Makes two elements tangential. You can make two circles or arcs tangential. You can also make a circle, or an arc, and a line tangential.
Lock
Locks an element from being modified. To unlock an element, select Modify 
, select the lock glyph next to the element in the graphic view, and press DELETE.
Change
Modify
Activates modify mode. Use this command to change or delete elements that you have drawn or relationships that you have defined.
To modify an element, click Modify , select the element, select an element handle, and move the handle to the new location.
To delete a constraint or relationship, click Modify , select the indicator (
or , for example) in the graphic view, and press DELETE.
Extend
Extends an element until it intersects with another object that you select.
Trim
Shortens an element to where it intersects with another object that you select. Select the element on the side to trim.
Sketching Options
Coincident Constraints to External References
Select to constrain sketching elements to objects in the model. Constrained sketched elements move when the model object moves.
Constraint Annotations
Shows or hides the constraint indicators in the graphic view.
Working Constraint
No Constraint (CTRL + 6)
Objects are free to move in any direction.
East
Y-axis and Z-axis coordinates are locked. Object moves freely along the X-axis.
North
X-axis and Z-axis coordinates are locked. Object moves freely along the Y-axis.
Elevation
X-axis and Y-axis coordinates are locked. Object moves freely along the Z-axis.
Elevation Plane (CTRL + 1)
Z-axis coordinate is locked. Object moves freely in the X-Y coordinate plane.
East-West Plane (CTRL + 3)
X-axis coordinate is locked. Object moves freely in the Y-Z coordinate plane.
North-South Plane (CTRL + 2)
Y-axis coordinate is locked. Object moves freely in the X-Z coordinate plane.
Select Interactively
Enables you to select the line or plane constraint from the graphic view.
Reset
Deletes all elements that you placed or undoes any modifications that you made to the sketch. The sketch is returned to the state when you activated the sketching controls.
Accept
Validates and accepts the shapes that you drew, or the edits that you made to a sketch,
as the shape to use in the calling command. Click Navigate Backwards to return to the calling command.
