Product Name: 25cm Curve Board
It is a tool used to draw non-circular curves with different radii. When drawing non-circular curves, you can use a curve board or a flexible curve ruler made of malleable material and flexible metal core bars.
When drawing, to ensure the smoothness and accuracy of the lines, it is necessary to first determine a sufficient number of points on the required curve according to the corresponding drawing method, and then connect these points with a curve board to form the curve.
Specific usage and steps are: '
① Draw some points on the curve according to the corresponding method.
② Use a pencil to connect the points sequentially to form a curve by hand; '
Find the line segment that matches the curve on the curve board and draw the line segment.
④ Use the same method to find the next segment. There should be a small common segment as a transition between adjacent curve segments, that is, there should be a small section that overlaps with the already drawn curve segment to ensure that the final curve is smooth and flowing.
