Note that the circle tool is really an ellipse and elliptic arc tool, for which we are using a special case of the ellipse, i.e. the circle. Now you should have a nice circle, with a solid black outline that is completely closed. If you have a Pac-Man shape or an arc, simply click the "make whole" button in the upper toolbar.
It is often very useful to use this feature if you are drawing a symmetrical diagram. Draw the left hand side, join the individual parts together, copy and paste the image, flip horizontally, then align and join. Hey presto! A perfectly symmetrical object. The align objects option allows you to precisely align two or more objects together.
The pencil holder, thumb screws, brass pivot and branches are all well built. They are used for scribing circles and stepping off repetitive measurements [5] with some accuracy. A reduction compass or proportional dividers is used to reduce or enlarge patterns while conserving angles. Ellipse drawing compasses are used to draw ellipse.
Seven circles theorem. In geometry, the seven circles theorem is a theorem about a certain arrangement of seven circles in the Euclidean plane.Specifically, given a chain of six circles all tangent to a seventh circle and each tangent to its two neighbors, the three lines drawn between opposite pairs of the points of tangency on the seventh circle all pass through the same point.
It can only be used to draw a line segment between two points, or to extend an existing line segment. The compass can have an arbitrarily large radius with no markings on it (unlike certain real-world compasses). Circles and circular arcs can be drawn starting from two given points: the centre and a point on the circle. The compass may or may ...
One way to draw using an oblique view is to draw the side of the object you are looking at in two dimensions, i.e. flat, and then draw the other sides at an angle of 45°, but instead of drawing the sides full size they are only drawn with half the depth creating 'forced depth' – adding an element of realism to the object.

A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science. A Venn diagram uses simple closed ...
