1. Open 3dmax first, then create a circle with a radius of 500mm in the top view, draw a star, set the radius 1 to 500, the radius 2 to 600, and the number of sides to 12. Then create a rectangle with a width of 500mm.
2. Then draw a straight line and turn on the snap switch. Stroke with a vertical side of the rectangle as a straight line, so that the length of the straight line is 500mm.
3. Then turn off the snapshot switch, select the rectangle, and press the delete key to delete. This leaves only three figures: circle, star and straight line.
4. Click the line, then select the lofting tool under the composite object, and then click Get Object to select the circle.
5. Then, when the input path parameter is 100, click "Get Graph" and select the star.
6. Click on "skin parameters" and remove the check of "sealing end" under the seal, so that the tablecloth under the frustum becomes hollow. Then, after a series of minor adjustments, the circles and stars were deleted. Click on the whole tablecloth and left-click it to convert it into an editable polygon.
In this way, a tablecloth was made with 3dmax.
