Convenient to use: the circle and straight line drafting set is an instrumental helper involving many measurement tools that are needed in drafting and drawing, by architects, engineers, draftsmen, builders, roofers, teachers and students. Extension beam design: there is an extension beam attached to the big compass for drawing large circles You can draw a larger circle without lots of measuring and connective dots. Practical geometry compass set: the rulers, triangles and protractors feature gradations for easy identification The robust plastic case is to protect and store these tools in one place in a backpack or desk. Quality tool sets: the compass kit set is made of zinc alloy steel which is sturdy, durable and easy to carry The rulers and protractors tool set is made of PS material which is light-weight, clear and heavy-duty. Sufficient quantity: you will get a package including 3 graphic compasses, 1 ruling pen, 1 dull locating pin, 1 extension bar safe pin, 2 pencil refills, 1 mechanical pencil, 2 triangular rulers, 1 piece 6-inch ruler, 1 piece 3.5-inch protractor, which are put in 1 shatterproof plastic box. Notice: If you receive the product and found the screw of compass is loose, do not worry, it is not a quality problem The loose screw makes it easier for you to turn the pencil lead down You can tighten the screw after using pencil lead replace divider part. 6 Inch protractor: Made of plastic, inch marks is up to 6 inch, centimeter marks is up to 10 cm Range of 0 to 180 degrees, and clear color allow you see the words, letters, figures on page through the protractor, it makes measuring easy. Integrated compass package: Compass comes with a clear box, contain 1 piece geometry compass and 1 box refill packaged in a transparent box, convenient for organized and carry. 2 Diverse tips Design compass:Stainless steel compass,solid and durable The opposite side of the pencil end is an adjustable separated jaw which allows you to fix the ink or paint. Wide application: 2 Piece math set are great for drawing circle and measuring angle, good for students, teachers, engineers, designers, artists, etc. Lock the protractor by turning on the Locked property in its track menu. Locking the protractor prevents it from making any changes to the scale. 
You can attach to any point mass track including a center of mass, particle model or data track.Īttaching the points automatically unfixes the protractor.
item in the protractor's track menu, then select the desired point mass tracks from the dropdown lists in the Attach Points dialog. To attach points, choose the Attach Points. This can be accomplished by creating a protractor and attaching its ends and/or vertex to the point masses. It is sometimes useful to measure the distances and angles determined by independent point mass tracks. Uncheck the Fixed Position checkbox in its track menu to allow these properties to vary independently from frame to frame. For finer control you can drag away from the vertex-a dashed line continues to connect the drag point to the arc arrow as shown.īy default, the protractor has a fixed position-that is, its vertex and arm positions are the same in all frames. Set the arc to a specific angle by clicking either the angle readout or toolbar field and entering the desired angle.ĭrag the center of either arm to move the entire protractor without changing the angle or orientation.ĭrag the arc arrow to rotate the entire protractor about its vertex without changing the angular arc. The arc arrow shows the direction (cw or ccw) of the arc and the angle readout and toolbar angle field display its value (positive if ccw, negative if cw). New protractors are placed at the center of the current viewport.Ĭlick and drag the vertex or circular end of either arm to adjust the arms. Multiple protractors can be created as needed. To create a protractor, click the arrow on the Measuring Tools button and choose New|Protractor from the popup menu. The ruler diameter is determined by the base length, and larger diameters show finer angle resolution. To hide the ruler, uncheck the Ruler box on the toolbar.
#Protractor angles full
It has a vertex, a base (solid) and measuring (dotted) arm, an arc arrow and an angle readout that displays in degrees or radians.Ī full 360-degree ruler (right image above) is also drawn by default. A protractor track is a tool for measuring angular arcs.
