Options
- Press A or the
Finish button to finish the spline, leaving it open.
- Press O or the
Close button to close the spline, that is, a curve will be added from the last point to the first one to form a face. At least three points are required to form a face.
- Press W or the
Wipe button to remove the curve segments already placed, but keep editing the spline from the last point.
- Press U or the
Set WP button to adjust the current working plane in the orientation of the last point.
- Press X, Y or Z after a point to constrain the next point on the given axis.
- To enter coordinates manually, simply enter the numbers, then press Enter between each X, Y and Z component. You can press the
add point button when you have the desired values to insert the point.
- 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 BSpline tool will restart after you finish the spline, 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 spline will create a filled face (DataMake Face
true); if not, the closed spline will not make a face (DataMake Face false).
- Note: the spline should not be filled if it intersects itself, as it won't create a proper face. If the spline is filled but no shape is visible, manually set DataMake Face to
false to see the spline.
- 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; curve segments already placed will remain.
