Clicking constructs a node at the nearest intersection point of construction entities, while in “constrained”
drawing, or construct a node at the position on the drawing directly under the cursor in “free” drawing.
The options , , and allow creating nodes lying on the selected entities.
To construct a node relative to another node, the option is used.
The options , and help creating nodes based on fragments and on the lines of 2D projections.
Nodes Based on Construction Entities
There are two main ways of creating nodes at intersections of entities in the command “N: Construct
Node”:
1. Move the cursor over an intersection of two
entities and click . A node is created at this
point.
2. Subsequently create two construction entities. The node is created at their intersection point. Should
there be two or more intersections, the one is used that was nearest to the cursor at the time of the last
entity selection. The options used for selecting various-type construction entities are , , and
.
The second way of creating nodes is recommended on crowded drawings and in the cases when more than
two entities intersect in one point.
Examples of node creation:
,
,
,
To create a node on a construction circle, select the circle using the option . A
node will start rubberbanding along the circle. The position of the node on the
circle can be defined roughly by mouse clicking , or exactly in the property
window or in the parameters dialog box (the option ).
