Dimensions<br />

If necessary, the size and position of dimension components can be arbitrarily modified, including tying<br />

nodes. This is done similar to defining the positions of dimension entity strokes for linear dimension type,<br />

using the options and .<br />

To define arbitrary positions of various dimension components, upon selecting the circle place the pointer so<br />

that the dimension fixation point (marked by a cross) assumes the desired position, and type <br />

or . The dimension position will be fixed (tied to the nearest node if using the option ), while the<br />

dimension leader jog will start moving following the pointer. Clicking now completes the dimension<br />

creation. Instead of clicking , one can once more type or to use the respective options<br />

– the length of the leader after the jog will then get modified. A subsequent click completes the dimension<br />

creation, while using or resumes dimension positioning, and so on.<br />

The additional option turns on the mode of continuous radius dimension creation at a common fixing<br />

point. This mode can be used for creating radius dimensions, originating at the same point, on several<br />

concentric circles. With the option on, upon completing one dimension creation (the one on the first circle),<br />

the system waits for dimensioning another circle.<br />

If the fixing point of the first circle dimension was tied to a <strong>2D</strong> node,<br />

then the dimensions on all following circles are tied to this node<br />

automatically. However, if the first dimension was fixed arbitrarily<br />

(by clicking or typing ), then a free node is created<br />

at that point, with all the rest of the dimensions tied to it.<br />

Drawing Leader Dimension<br />

For drawing dimension similar to one shown on the picture on the right, the<br />

option is used.<br />

After calling this option, it is necessary to indicate the fixing point (<strong>2D</strong> node)<br />

for tying the dimension. In the automenu the following option for picking the<br />

node appears:<br />
