The present subject matter relates to generation of a geometry corresponding to a cross-sectional profile of an object. In an example method, a sketch corresponding to the cross-sectional profile of the object is received by a computing device. The sketch is drawn by moving a pointer over a display unit of the computing device. Pixel points generated by the display unit are obtained by the computing device. The pixel points correspond to the sketch. Low-speed pixel points, from amongst the pixel points, are joined with straight lines. The low-speed pixel points are the pixel points at which a speed of drawing of the sketch is below a predefined speed threshold. The straight lines are processed by the computing device into the geometry of the object.
