After forming the spiral to complete the spiral drawing, it is necessary to realize the design of the spring. The drawing method is to draw the cross section of the spring on the plane perpendicular to the spiral, and the cross section can be a closed figure of any shape. In order to draw the cross section, the user coordinate system is rotated 90b around the X axis so that the user coordinate system at this time is perpendicular to the plane of the spiral. The drawing of the spring section is done on this coordinate system. When the spiral path and section are completed, the spring can be made by COPY replication and EXTRUDE stretching. Since the spiral is generated by multi-segment straight line approximation, after the spiral is drawn, the closed pattern can be directly used to stretch the guide along the spiral to form a spiral of 360b. If the spiral is replicated or the array is formed into a whole spiral, the twist of the spiral is caused. The spiral is a multi-segment straight line fitting. The cumulative error during the stretching process causes the spiral to twist. There are some gaps between the two spirals, which causes the spiral to be not smooth. We use the method of forming the spiral by segmentation, that is, First generate a spiral line, and convert the user coordinate system on this spiral line, draw the spring section to be stretched on the vertical plane of the spiral, and then copy or array the spiral line and the section, and stretch it piece by piece. The spiral obtained in this way is a spiral connected to the whole segment, and the error can be controlled within a reasonable range. This is a problem that resolves manual data entry.
