Placing Model Lines

Click Model tab (Model Line).
Click Modify | Place Lines tabDraw panel, and select a sketching option or Pick Lines to create lines by selecting lines within the model.
If you want to use a different line style than the one shown on Line Style panel, select one from the Line Style drop-down.
For information about creating additional line styles, see Line Styles. Note that line styles are not available for model lines created in sketch mode.

On the Options Bar, specify the following options as appropriate for the type of model line you are drawing:

If you want to…	then…
draw the model line on a plane other than the current value of Placement Plane	select a different level or plane from the drop-down. If the desired plane is not listed, select Pick, and use the Work Plane dialog to specify a plane. See Setting and Showing the Work Plane.
draw multiple connected line segments	select Chain.
offset the model line, either from the cursor position or from an edge you select in the drawing area	enter a value for Offset.
specify a radius for a circle or curved model line or for filleted corners on a rectangle or filleted joins between chained lines	select Radius, and enter a value.

In the drawing area, draw the model line, or click an existing line or edge, depending on the sketching option you are using.
Tip: After you click to specify the start point of a straight model line, you can quickly set its length by typing a value for the temporary dimension that displays with the line. Likewise, you can enter a radius value for circles or curves, 2 radius values for ellipses, or —for polygons— the distance from the center to the vertices or sides.

Like components, model lines can move with nearby elements, provided they are sketched parallel to that element. For example, if you draw a wall and then draw a line parallel to that wall, the line can move with the wall if you select the Moves With Nearby Elements option on the Options Bar, or choose it from the properties of the line. An arc line can move with an arc wall if the 2 are concentric. See Moving Lines and Components with Walls.
