Ellipses highlight and the cursor will gain a glyph . To create a construction line now, simply point the cursor to a projection entity – ellipse or elliptic arc and click . The following options will become available in the automenu: Ellipse Parameters Set ellipse parameters Cancel selection When creating or editing ellipses, one can control various parameters. The geometrical parameter (the semiaxis length) can be defined in transparent mode using the property window. The general system parameters are controlled via the complete ellipse parameters dialog box via the option: Set ellipse parameters Axis. The length of one of the ellipse’s semi-axes. The input can be a number, a variable or an expression. Value. Displays the numerical value of the “Axis” parameter. Level. Places the ellipse on a certain visibility level. Layer. The name of the layer the ellipse belongs to. Set as default. Setting this flag means, the current dialog box settings will be used as the defaults for ellipses creation in future. Editing Ellipses Editing ellipses, just like any other construction entities is done via the command “EC: Edit Construction”. Keyboard Textual Menu Icon “Edit|Construction|2D Construction” This command allows changing ellipse parameters, assigning a name to an ellipse and deleting it. An ellipse can be selected by pointing at with the cursor and clicking or via the option: Select Ellipse The ellipse editing command, “EC: Edit Construction”, can also be accessed from within the command “EL: Construct Ellipse” via the option: Execute Edit Construction command Detailed description of the command “EC: Edit Construction” can be found in the earlier chapter “Lines” (section “Editing Lines”). 223
Fundamentals. Two-Dimensional Design NODES 224 Node is a point whose coordinates are calculated depending on the node parameters or position of other model elements. Nodes are important construction elements in T-FLEX CAD. They represent start and end points of graphic lines. Nodes are directly involved in creation of most of the graphic elements. They also play an important role in creation of construction entities. Creating Nodes T-FLEX CAD supports nodes of various types, depending on the relation with other model elements. Most common are nodes constructed at an intersection or at a tangency point between two construction lines. Such nodes are displayed as small x-shape crosses. Other types of nodes are displayed differently on the screen. There are following types of nodes: Node at intersection of construction lines. Such nodes are used most often in creation of parametric models. Its position is defined by the position of two construction entities and their intersection to which the node is related. In the case of multiple intersections between the entities, the particular intersection shall be identified. Free node is defined by the absolute X and Y coordinates in the model coordinates. The values of a free node coordinates can be defined by variables. Such nodes are of limited use in parametric models being created, however, these are widely used in development of sketches, various diagrams and technical figures. Free nodes are useful in the cases when there is no strict requirement on positioning points of the image. Node from fragment is defined by the position of another node located on a fragment of an assembly. This type of node is necessary for creation of parametric assemblies. It is used for relating some element of an assembly with a point on a fragment of this assembly. Node created relative to another node. Its position is defined by an offset from another node. The offset values can be defined by constants or by variables. A node of this type can be used as an auxiliary fixing point in the cases when some element should be snapped at an offset position of the base node rather than to that node directly. Node lying on a construction entity, at the specified distance from another node along the entity. Node – a characteristic point of a construction entity. Among this type are nodes lying at a circle center, at a start or end point of a spline or other curve. Node on a curve, dividing the curve in a specified proportion. Nodes placed at characteristic points of elements. This type includes nodes on dimension witness lines, on leader notes, at the ends of lines created by copying, etc. For a point to become a node, the node needs to be created. This can be done in various ways:
