Now many friends have installed the caxa software on their computers, but some of them still don’t know how to make a cone expansion diagram, so the editor below has brought a graphic tutorial on how to make a cone expansion diagram with caxa. Let’s take a look. !
1. Draw the circular platform you need to expand in caxa.
2. Extend the two busbars of the circular cone until they intersect at one point.
3. The intersection point obtained in the above step is the center of the circle, and the two endpoints from the intersection point to the generatrix of the circular cone are the radii. Make two concentric circles. Then the fan-shaped surface of the circular cone will be on the ring obtained by these two concentric circles. . Because the circular cone expansion is based on the busbar.
4. Measure the radii of the two circles drawn in the previous step. The radius of the small circle is R1 and the radius of the large circle is R2. At the same time, measure the radius of the upper and lower circular surfaces of the circular table. The radius of the small circle on the upper part is r1 and the radius of the large circle on the lower part is r2. As we all know, the arc length of a circular cone after expansion is l=θ*r, where θ is the expansion angle, l1=θ*R1, l2=θ*R2. The arc length of the sector after the circular cone is expanded is the circumference of the upper and lower circular surfaces of the circular cone, l1=2π*r1, l2=2π*r2, then the expansion angle θ=2π*r1/R1=2π*r2/R2 can be found, unit is radians, converted into degrees, then θ=360*r1/R1=360*r2/R2. According to this formula and combined with the measured dimensions, the expansion angle θ is obtained.
5. After finding the expansion angle θ, use a bus as the starting bus and rotate the bus at the expansion angle θ to obtain the terminal bus.
6. Through the above method, the expanded view of the circular cone is obtained, which is the shaded part in the picture. For the expansion of the cone, it is simpler. Just draw the outer big circle according to this method to get the complete expanded fan shape.
