Making a Line Normal to Another Line

The Normal tool in the Constraint toolbar enables you to make a selected line normal to an existing line.

First, select a line.
Then, select a line that will define the position of all the lines.
Finally, select the Normal tool.

If none of the lines are restricted by pre-existing constraints, the line that is selected first becomes normal to the line that is selected second.

If a line is restricted by pre-existing constraints, whenever possible, the independent line becomes normal to the constrained line.

Note: If the existing line is not in the current sketch, you must add it to the sketch as a reference entity.

Make a line normal to another line

Select the Add Constraints button from the Sketcher toolbar.

The cursor will be a pointer-and-grid symbol.

Click a line that you wish to make normal to another line.

Click the line to which the line selected in step 2 will be normal.

Click the Normal tool .

The line selected first (in step 2) moves to be normal to the line selected last (in step 3).

In the example above, none of the selected lines were previously constrained. If a line is already constrained, whenever possible, the independent line becomes normal to the constrained line.

Notes:

You can also first pick the entities to constrain (while in Select mode), then select the Add Constraints option, then choose the desired constraint.
Edit functions are restricted by pre-existing constraints. An entity will not be edited if underlying constraints do not permit. If required, you can break an entity's constraints to make it independent of all other entities.
