Drawing and controlling spline curve in SolidWorks

The method of drawing and controlling spline curve in SolidWorks

the method of drawing and controlling spline curve in SolidWorks 2001 in the modeling design of industrial products, in order to achieve good visual effect of products, spline curves are often used as sketches to establish features. This paper will briefly introduce the method of drawing and controlling spline curve in SolidWorks2001. 1. Drawing of spline curve

spline curve is formed by smooth transition through a series of points, which are called spline value points. SolidWorks2001 provides two methods to draw spline curves, namely, alternating spline curve drawing method and dragging method

n "the urgently needed new materials cannot be found, the ones that can be found cannot be made, and the ones that can be made cannot be made well. Alternate spline curve drawing is a method of generating spline curves by clicking on the place where the spline curve type value points pass.

1) create a new sketch and click the" spline curve "button

2) click "point 1" ~ "point 4" as shown in Figure 1 (a) in turn, and double-click at "point 5" to form the spline curve as shown in Figure 1 (b)

3) click the "spline" button again to end the spline drawing

n drag type

drag type drawing method can install various special fixtures and accessories to drag each section of the spline curve to form a spline curve

1) create a new sketch and click the "spline" button

2) press the mouse at "point 1" as shown in Figure 1 (a), drag it to "point 2" and release the mouse

3) drag to "point 3", "point 4" and "point 5" successively, and double-click the mouse at "point 5" to form the spline curve as shown in Figure 1 (b)

4) finish spline drawing

2. control of spline curve

the value points of spline curve can be used as control marks, and the shape of spline curve can be changed by changing the position of the value points of spline curve. When drawing a spline curve, the number of spline value points is initially determined by the number of mouse click points (alternate spline drawing method) or different curve segments dragged (drag type)

welcome to visit the large-scale manufacturer of Jinan new era assay instrument Co., Ltd.

select the spline curve and right-click it. In the pop-up shortcut menu, you can use a series of tools such as "insert spline curve type value point", "move box", "check curvature" to control the shape of the spline curve (as shown in Figure 2) transfer investment center of China's chemical industry nbsp; Aim at new materials:
