Press R or click the checkbox to toggle relative mode. If relative mode is on, the coordinates of the next point are relative to the last one; if not, they are absolute, taken from the origin (0,0,0).
Press T or click the checkbox to toggle continue mode. If continue mode is on, the Wire tool will restart after you finish the wire, allowing you to draw another one without pressing the tool button again.
Press L or click the checkbox to toggle filled mode. If filled mode is on, a closed wire will create a filled face (数据Make Facetrue); if not, the closed wire will not make a face (数据Make Facefalse).
Note: the wire should not be filled if it intersects itself, as it won't create a proper face. If the wire is filled but no shape is visible, manually set 数据Make Face to false to see the wire.
Hold Ctrl while drawing to force snapping your point to the nearest snap location, independently of the distance.
Hold Shift while drawing to constrain your next point horizontally or vertically in relation to the last one.
Press Ctrl+Z or press the Undo button to undo the last point.
Press Esc or the Close button to abort the current command; line segments already placed will remain.
