| ## page was renamed from CUPRO Syntaxis <<TableOfContents()>> = Command handling = Prof is a command line (cli) program. We think that is the most efficient way to create profiles. Because there are many options: * Reminders are written on the command line, get used to read the command line (cli), drag up cli to get a few more lines and or toggle F2 during the command when needed. * For specific profiles there are commands acting as short-cut. * Be aware of pressing ENTER for defaults, they make life easier. = Steps = Every new shape you create is made in a number of steps. These steps are more or less standardized. In summary: * Choose from '''Shapes''' * Direct input like "UNP 100*50" or "RLC 40" or "L 2*2*1/4". * Choose main group like "warm rolled" or "math". Then choose subgroup like "IPE" or "Reuleaux". * Enter UCS for '''Positioning''' * Enter '''Geometry''' and let program generate curve(s) for your shape. * You can accept this shape or '''Modify''' it: Change position, extrude with options as solid. * Let program finish restoring settings and UCS prior to command start. = Shapes = This program is able to draw many shapes - and that is a lot! To be able to enter shapes fast and easy, a good structure is needed. On the other hand, nomenclature is very different internationally, though tempting, we cannot always use it directly. A warm rolled L-profile is designated the same but has different standard sizes as defined in the international standards. Defining main groups: * W, Warm rolled: Deformed products like channels and I-beams. * C, Cold rolled: Sheet based products with constant thickness like pipes and HSS. * E, Extruded: Products with sharp corners like aluminum L-profiles. * I, Infrequent: All other products, except: * S, Splines: Several standards. * G, Gears: Involute shapes. * M, Math: Closed and open mathematical shapes. Defining standard types: * Profiles with table drive parameters, like warm rolled beams. * Profiles with free parameters. Defining regions for standards: * EN, Europe * BS, Britain * IS, India * JIS, Japan * GOST, Russia * ASTM, US * ... and more. = Positioning = PROF works both 2D and 3D. To place a profile in 2D, an insertion point and angle is required. 3D users are used to make a UCS first and or use Dynamic UCS. How to serve both groups? * 2D insertion point equals point 0,0 in 3D * 2D angle equals x-axis in 3D On the cli you'll see this as the solution: {{{ Shapes are inserted on 0,0 and aligned to X-axis of the active UCS. Specify new UCS origin or [Origin only / X-axis only] <Press ENTER to continue with current UCS>: }}} This boils down to four options for insertion: * Create new UCS for insertion, with origin and angle of X-axis. * Just move origin (0,0) of running UCS. * Just rotate X-axis of running UCS. * Accept running UCS for placement. = Settings = Settings are written to a file and retrieved. Location is visible at program start (press F2). == About units == Basic principle: Everything works unitless. So if you work in inches and insert an imperial product or if you work in mm and insert a metric product, everything is okay. Problems could arise when you work in inches and insert a metric product or, when you work in mm and insert an imperial product. How do we deal with that? * The program makes an educated guess for units. * You are given the options to set units. * As a last resort, you can always scale things manually. === Educated guess for units === * First, INSUNITS is examined. If this drawing setting is set to "1" (Inches) or "4" (mm), the decision is made. This means that units are converted without intervention. * If INSUNITS has another value, but not "0" (Unitless), inserted shapes are scaled. For example, if INSUNITS is "6" (meters), a metric profile will be scaled with factor 0.001 and an imperial profile will be scaled 0.001*25.4. * If INSUNITS equals "0" it becomes harder. If, in this order, INSUNITSDEFTARGET and INSUNITSDEFSOURCE provide a means to do a scale calculation, it is done. * If everything is set to "0" (Unitless), then no scaling is done and shapes are inserted "as is". === Options to set units === During execution you can change settings. When settings are detected, other than "0", "1" and "4", suggestions are made. |
