Element Replacement When using the command “RL: Replace Element”, the target element should not be a child of the source one. Otherwise, a message is output about the encountered recursion. In the next example, the “Line 2” is constructed relative to the base line, “Line 1”. In turn, the lines “Line 3” and “Line 4” are constructed relative to the “Line 2”. A circle is created with the center at the intersection between the “Line 2” and the horizontal line in such a way, that it intersects the “Line 3” and not the “Line 4”. An attempt to replace the “Line 1” by the “Line 2” in this model causes the message about recursion. The command may also fail when some drawing element position cannot be defined relative to the target element. For example, when creating the drawing of the above example, one of the nodes was defined as the node at the intersection between the circle and the “Line 3”. An attempt to replace the “Line 3” by the “Line 4” will cause an error message, since the system will not be able to define the position of this node after the replacement. 455
Fundamentals. Two-Dimensional Design DRAWING MODIFICATION VIA DIMENSIONS 456 T-FLEX CAD has the capability of modifying the model (3D model or 2D drawing) by using the dimensions. The user specifies the new dimension nominal value, and the system automatically rebuilds the 3D model or drawing based on parametric dependencies. Such editing is supported for both 2D dimensions (that is, dimensions in a drawing) and for 3D dimensions (dimensions in a 3D model), as well as their corresponding dimensions on 2D projections. Decides that, there is a provision for automatically calculation of all dimensions to the middle of the tolerance range. Dimension value modification command In T-FLEX CAD it is possible to edit both the drawing and the 3D model by modifying the nominal values of dimensions created therein. The command “PE: Set Dimension Values” is used for this purpose. The command can be used either in the “transparent mode” or explicitly called by one of the following means: Keyboard Textual Menu Icon “Parameters|Dimensions|Set Value” Besides that, this command is available in the context menu when selecting a dimension (whether a 2D dimension or a 3D dimension). To enable the command in the transparent mode, you need to set the flag “Dimension edit is transparent” in the command “SO: Set System Options”, the tab “Preferences”. After that, selecting any dimension value string by launches the command “PE: Set Dimension Values”. The selected dimension value is highlighted, ready for editing. If the transparent mode is not set for this command, dimension values can be selected for editing only after the explicit command call. When a dimension value is modified, the system tries to find one construction element, whose modification affects the dimension value. If such element is found, it will be modified according to the requested dimension value. Otherwise, the drawing will stay unchanged. If several such construction elements are found, then the system will select the one of them, whose modification will affect as few other dimensions as possible. When the position of a construction element is modified, other 2D elements will be adjusted as well (including construction lines and/or graphic lines, dimensions, leader notes, etc.), that are related with it. If the position of the elements being adjusted was driven by variables, then the system will query you for the automatic adjustment of their values. Upon calling the command, the following icons appear in the automenu: Finish Value input Exit command
