Example of Creating «Woody» Hatch Creating Custom Lines and Hatches The custom hatch creation mechanism allows creating even more complex hatches, for example, a “woody” hatch. To create this type of a hatch, a pattern was created as shown on the figure. An appropriately arranged placement of direction nodes yields a hatch imitating wood texture. 707
Fundamentals. Two-Dimensional Design CREATING LIBRARIES OF PARAMETRIC ELEMENTS 708 T-FLEX CAD offers a rich library of standard elements included in the application installation package. The libraries of standard elements speed up the design process and allow the designer to concentrate on the actual development, rather than on drawing bolts and nuts alike. Besides, T-FLEX system provides tools for the user to define one's own standard elements, that support wide range of productivity improvements. Designers often use families of elements whose members are mostly identical, often with the only difference in the dimension values, having to spend time just to draw such an element. This issue can be resolved by creating a standard parametric element in T-FLEX CAD system. A big advantage of T-FLEX CAD compared to other systems is the provision for the user to create own standard parametric elements. This does not require knowledge of any programming language. The user can create any objects, from drawings and 3D models to dialog boxes for fragment insertion. T-FLEX CAD provides special commands for this purpose. Another positive feature is that any library element is an ordinary T-FLEX parametric drawing. Creating Parametric Library Elements Parametric library element creation can be divided into several steps: 1. Creating databases (if necessary). 2. Creating variables, including those relying on databases. 3. Creating a parametric drawing and/or 3D model. 4. Creating fixing vectors and fixing LCS; 5. Creating 2D and/or 3D connectors; 6. Creating a dialog box of fragment’s parameters. 7. Adding the element to the library. Some of these steps can be skipped. For example, you may not need a set of values from a database, or you're not creating a 3D model, 2D or 3D connectors. Let’s review each step by an example. Consider a bolt GOST 7795-70. The file for this example can be found in the library “Examples for user manual” in the folder “2D Design\Library of parametric parts creation\Bolt GOST 7795-70.GRB”. The parameters of this bolt should update from the database depending on the input diameter and length. The bolt has several implementations. Both the drawing (the three views: front, left and top) and the 3D model should adjust to each implementation. The bolt will be used as a fragment in other drawings.
