Making Connections gibbscam

Most connections are made automatically by the software. If the Point button is chosen on the Geometry Creation palette and two features on the screen are selected, the software will automatically create a connector at the intersection or tangency of the two features. If a connection cannot be made automatically, a plain point will be created at the intersection or tangency of the two features. Once a feature has two connectors on it, it is considered fully connected. A connection must be broken on the original shape before another connection can be added to it.

Connect 1

 

If a plain point exists at the intersection or tangent point between two yellow features, that point can be turned into a connector. This is accomplished using the Connect-Disconnect button in the Geometry Creation palette, which is described in more detail in Connect/Disconnect, or you may use the right mouse menu (see Connect / Disconnect) to connect selected overlapping/tangent shapes. To change a point into a connector, use the Ctrl key to select the point and the two features that intersect at the point. These should be the only items that are selected. Click the Connect-Disconnect button. The point will change to a blue square. If one (or both) of the features is already connected to another feature, it will turn blue and trim with a square yellow endpoint.

The four descriptions listed below explain possible reasons why the Connect-Disconnect button will not perform the desired function.

One of the features already has two connections on it.
The point is not tangent to or is not exactly at the intersection of the two features.
The wrong geometry is selected, either too much or too little in most cases.
There are multiple features on top of one another.

The best way to tell if there are multiple features on top of one another is to turn on View > Labels. If all of the numbers are clearly visible, there is only one feature at that location. If the numbers are jumbled, there are probably features on top of each other. Try deleting features and re-drawing until there is only one feature left. If the last feature is deleted by accident, use the Undo item from the Edit menu to back up a step. Refer to Cleanup in the Plug-ins Guide for an alternate way to remedy this issue.

Open Shapes

To terminate the last feature of a shape and create an open shape, a point needs to be created at the location where the shape is to end. The feature to be terminated must be yellow to begin with. Select the point and the feature and click the Connect-Disconnect button. The point will become a yellow square. If the feature already has one connector or terminator on it, it will turn blue and trim.

Circles

When connecting circles, the shortest side of the circle will connect and the rest will be trimmed away. To use the larger portion of the circle, select the circle after it has been trimmed and use the Reverse Arc choice from the Modify menu. An alternate solution for circles may be created using the –R function. See -R Creation.
