“Free” Nodes Nodes The main approach to creating drawings in T-FLEX implies use of nodes on the intersections of construction entities. However, the system also supports so-called “free” nodes. These nodes are not the points of entity intersections; rather, these are defined in absolute coordinates. Such nodes can be used just as well as usual “constrained” nodes for creating either construction entities or graphic elements. Free nodes are displayed as squares. To create such nodes, turn on “free” drawing mode in the command “N: Construct Node” by using the option / . Object snapping engages in free drawing mode similar to that provided in the sketching command. Besides, one can use the grid, with its settings defined in the command “QG: Change Grid settings”. The grid helps positioning created nodes more accurately. To create a node, point the cursor to the desired location on the drawing and click . The node will be created right under the cursor. The exact position of the node on the drawing can be specified in the property window. A feature of “free” nodes is the provision for moving such node or a group of nodes and, therefore, all elements related to them, by the command “ЕN: Edit Node”. This is impossible for “constrained” nodes. The latter can only be moved by relocating construction entities used for the nodes creation. As in the case of other drawing elements, multiple selection is done by the option , or by clicking while holding down the key (adding to the list of selected), or key (excluding form the list of selected). Generally speaking, the following options are available in the command “ЕN: Edit Node”: Set selected Element(s) parameters Create Name for selected Element Join free Nodes Break (split) Node Convert to Free Node Select existing Node Select element from list 229
Fundamentals. Two-Dimensional Design 230 Select Other Element Delete selected Element(s) Cancel selection Let us elaborate on the options and . These options affect a group of nodes, one of which can be constrained, and the rest - “free”. The option unites several nodes into one, adjusting the graphics accordingly. The option splits a node at a meeting point of multiple graphic entities. Each of the entities gets its own node whose position you can modify. Keep in mind that “free” nodes are not recommended for use in parametric drawings. Drawings based on free nodes are similar to those supported by other CAD systems, and lack the advantage of parametric geometrical relations. The option is available for nodes, not related to construction entities (for example, nodes from fragment or from 2D projection). This option allows breaking the relation between the node and its original references by converting it into a free node, whose position will not change under modifications to the original reference elements. The option is an additional tool for multiple selections. To add a node to the list of selected, simply engage this option and pick the desired node. Nodes from Fragment. Node Names This way of node creation is quite important for support of parametric assemblies. The nodes from fragments provide the means for “tying up” construction entities and graphic elements of the current assembly to the fragment. For example, you assembled a bushing on your drawing by the command “FR: Create Fragment”, and now want to create a dimension on the outer diameter of the bushing. Since a dimension can’t be created without nodes, you need to create two nodes from this fragment. Nodes from fragment can be created automatically upon assembling the fragment, if the respective flag, “Create Named Nodes Automatically”, is set among the system options (the command “SO:
