1.2.3 Create a new model<br />
To draw a set <strong>of</strong> non-concentric circles, first we need to have three concentric circles <strong>using</strong><br />
function ”Operate on arc Segments”. First we should mark some nodes <strong>using</strong><br />
“Operate on nodes”, then we switch to function . Select 2 nodes one by another to draw<br />
an arc segments in between, <strong>and</strong> then we will have half <strong>of</strong> the circle. Now we need the other<br />
half so we select these 2 nodes again but this time change the selection order. In this way, we<br />
will be able to make all three circles.<br />
Figure 1-24 New model step 1<br />
Our model is a non-concentric cable, so we shift the inner circle, <strong>using</strong> ”Move/Remote the<br />
selected Object”. First switch to function <strong>and</strong> select the inner circle. Press , shift it<br />
along X-axis for 3 units.
