properties of the variable controlling the<br />

nut’s diameter.<br />

For created connectors, let us indicate graphic<br />

lines, as associated elements, on the<br />

corresponding views of the bolt – this will<br />

simplify fixing to the given connector.<br />

Also, for <strong>2D</strong> connectors it is required to<br />

specify «insertion rules». When fixing a nut to<br />

the bolt’s connector, it is usually required to<br />

specify additional translation along the X-axis<br />

of the connector.<br />

By the same principle, let us create 3D<br />

connector on the 3D model. For the 3D<br />

connector let us create two named values:<br />

“DiameterOuterMetricThread” (bolt<br />

diameter) and “ThreadPitchMetric”<br />

(pitch of the bolt’s thread).<br />

Having created connectors, we prepared a<br />

basis for convenient fixing of other fragments<br />

of the assembly to our fragment. Next, let us<br />

return to the variables editor of our model and<br />

specify the following value of the connector:<br />

“DiameterInnerMetric” for the<br />

variable “d”. The same named value was<br />

specified for the connectors entering the<br />

library of openings. As a result, when the<br />

fragment of the bolt is inserted into the<br />

assembly by means of fixing to an opening’s<br />

connector, the actual bolt diameter will be<br />

defined automatically.
