This chapter gives basic ideas and recommendations on editing a 3D model and its related elements of a 2D drawing in T-FLEX CAD. By editing, we mean certain user actions aimed at making changes to an existing 3D model. There could be various reasons for editing:
1)correcting model flaws in the event of getting critical errors in the diagnostics window;
2)introducing improvements to existing model geometry, rearranging or rectifying a model, inserting sequences of operations in the middle of the model tree;
3)rearranging graphic elements in a drawing or in 2D constructions. Replacing elements. Resolving recursive references;
4)redefining geometrical or other properties of individual model elements;
5)modifying variable values;
6)modifying the model structure, reordering operations within the model tree;
7)modifying the methods of snapping and relations between 3D assembly elements, optimizing mates and setting up the function of a mechanism model;
8)deleting elements, excluding model objects from a sequence of related elements. Deleting sequences of related elements, deleting “extra” elements. Other.
A T-FLEX CAD model is usually a parametric one. Therefore, depending on a case it may become necessary to undertake a group of measures aimed at editing the model, since certain changes, once introduced, often cause a need to correct other relations. Therefore, before going ahead with profound editing, it is advisable to do some research and prepare the best plan of actions. When you do such preparations, you may face the following tasks:
1)identifying (researching) the model structure and the steps and methods of its creation;
2)identifying the sequence of related parents and children for a given model element;
3)finding elements:
•operations;
•3D construction elements;
•2D construction or graphic elements;
•variables that control the specific parameters;
4)tracing parametric dependencies: geometrical relations and element dependencies on variables;
5)geometry measurements and checks;
6)identifying invalid elements and the reasons behind model regeneration failures.
In this chapter we review the system tools that may be useful in various scenarios of the editing process. The specifics of editing certain elements is given in dedicated chapters of the documentation, which describe the workflow specifically for those elements.
We recommend to set aside a backup copy of the source file before proceeding with significant modifications to the model structure.
