Graphic Lines
To create a segment:
Select start node. If the selected node is on the intersection of several lines, then use the option for
specifying the line to apply graphics at. If upon typing key the construction line is not highlighted,
the selected node may not belong to the line. This means, a wrong node was selected.
Select end node. This completes creation of the graphic line between two nodes.
After creating a segment, the end node stays highlighted and becomes the start node for the next
graphic line. If you want to create a graphic line starting elsewhere, press or for
canceling the current node selection.
To define the start or end point of a graphic entity, simply place the cursor at the desired location and click
. In “constrained” drawing mode, clicking selects the node at the nearest intersection of construction
entities, if exists; otherwise, a node will be created at this intersection and then get selected. In “free”
drawing mode, either a new node is created, or an existing one is selected. An existing node is selected if the
graphic cursor is within the “finding” zone around the node. The size of this zone is defined by the parameter
“Node join distance” in the command “Customize|Options…|Preferences”. The size is defined in pixels.
The option works similar to the click , however, unlike the latter, it only allows selection of existing
nodes. New nodes won’t be created.
The options , , and allow selecting construction
entities of the respective types. The option behavior depends on the
current state (whether there is already a pre-highlighted node or
construction line).
The following is the way to create a full curve:
Select a respective construction entity by typing , or
, in a state when no node is selected.
To create a graphic line as a segment of the underlying construction line, do the following:
1. Select the start node for the segment (arc).
2. Select the intended construction entity. If a construction line does not get selected, that means the
selected node does not belong to the line, and the arc can’t be created starting from this node.
3. Select the end node of the segment (arc).
Then the arc will be created from the start to the end node. Please keep in mind that closed curves, such as a
circle, are divided by two nodes into two arcs. The arc will be created nearest to the cursor at the time of
selecting the end node.
