Nodes Set System Options”, “Fragments” tab). In this case, nodes will be created upon assembling the fragment based on all named nodes in the fragment. Besides, nodes from fragment can be created automatically when creating dimensions and other elements in the object snapping mode, if the flag “Create Nodes on Fragment Nodes” is set on the “Snap” tab of the command “SO: Set System Options”. Nodes from fragment can be created in the command “N: Construct Node”. With the object snapping mode engaged and the flag “Create Nodes on Fragment Nodes” set (the tab “Snap” of the command “SO: Set System Options”), a node from fragment is created as follows. Move the cursor over an end of a fragment graphic line. A node will highlight at the end of the line, with a tooltip saying “Fragment Node”. Clicking creates a node from fragment. With the object snapping mode off, first select a fragment via either of the options, or . The selected fragment will be highlighted. To create a node, simply specify the desired node on the fragment by selecting it in the list of the fragment nodes. The named nodes will be highlighted if exist in the fragment and the following option is set, Show Fragment Node Names After that, nodes from fragment can be created by pointing the cursor to the desired nodes among the highlighted ones and clicking . The nodes from fragment are displayed as crossed diamonds. The option highlights and makes available for selection all nodes that exist in the fragment. Show all Fragment Nodes To assign a name to a node of a fragment drawing, use the following option under the command “ЕN: Edit Node”: Create Name for selected Element Any name is allowed. The node now becomes named and can later be “exposed” upon assembling this drawing elsewhere. Once the nodes from fragment are created, make the dimension via the command “D: Create Dimension”: 231

Fundamentals. Two-Dimensional Design Nodes from 2D Projections 232 To create nodes based on the entities of 2D projections, one can use the option . Upon calling the option, select the desired projection by . The selected projection will be highlighted. After that, moving the cursor over the endpoints of graphic entities on the projection will highlight their nodes. Clicking creates a node from projection. Option allows the user also to project nodes from a 3D model. After calling the option and selection of projection, it is sufficient to indicate a required 3D node (in 3D window or in the tree of a 3D model). A free node, which is a projection of the given 3D node, will appear on 2D projection. Nodes Lying on Characteristic Points of Entities Such nodes can only be created in the object snapping mode, with the respective option checked on the “Snap” tab under the command “SO: Set System Options”. This type of nodes includes nodes lying on dimension witness lines, leader notes, tolerances, as well as on the endpoints of graphic lines copied from or belonging to 2D projections.
