Description
MSYU measuring rolling ruler/drawing roller ruler/parallel ruler/multifunctional drawing design ruler – Best for drawing-vertical lines, parallel lines, charts, angles, 3D drawings, horizontal lines, circles, graphs, musical-note etc. – The ruler allows me to make my guidelines quickly. The roller keep track of the distance between lines. – The measuring ruler can be applied to multi-functional drawing, including quadrants, squares circles, angles, crosshatching, and vertical and horizontal parallel lines. – It is with protractor, sliding roller, parallel scale, circle, auxiliary drawing. How to use: The use of protractor: Align the center of the protractor on the edge of the ruler with the vertex of the surveying foot, and at the same time, coincide the scale of the protractor with the datum line, then various angles can be measured on the edge of the ruler. Example:Draw the arc and curve – Insert the pen into the small hole at the ruler end to make the center of the circle, insert another pen into another hole and rotate the ruler body 360° to draw a circle. – If the radius between the 2 holes is different or the rotation ruler body is different, different circles or arcs can be obtained.
