| '''trajpar''' is a system parameter in [[Creo Elements/Pro]] that varies from 0 to 1 across the length of a given path. It is used to create complex [[geometric]] and non-geometric shapes that vary in dimension along the length of any given path.
| |
| | |
| ==Naming==
| |
| trajpar derives from the words: '''''traj'''''ectory '''''par'''''ameter. It is a [[pseudo]]-variable as it is controlled not by any mathematical representation, but by the physical representation of a path, i.e. a ''trajectory''.
| |
| | |
| ==Syntax==
| |
| sd3=evalgraph('graph1',trajpar*100) Where sd3= A variable inside the variable section sweep that will be driven by a graph feature called 'graph1'
| |
| | |
| ==Uses and notability==
| |
| trajpar can be used with various [[math]]ematical functions to create alternating, flaring, bowing or [[sinusoidal]] protrusions. It is primarily used in conjunction with the ''variable section sweep'' command in Creo Elements/Pro but can also remove material if desired.
| |
| | |
| trajpar typifies what makes Creo Elements/Pro different from many other CAD software systems. The level of complexity and control given to the user is much greater than, for example other design or engineering software like [[SolidWorks]] or [[Alias (Mac OS)|Alias]]
| |
| | |
| ==Samples==
| |
| To create an [[undulating]] wave, a sinusoid might be desired:
| |
| :<math>d1=sin(trajpar \cdot 8\pi)</math>
| |
| | |
| A flare:
| |
| :<math>d1=1 + trajpar^2</math>
| |
| | |
| etc., where d1 is the dimension to be controlled.

Nice to meet you, my title is Ling and I totally dig that title. For years she's been living in Kansas. My occupation is a manufacturing and distribution officer and I'm performing fairly great financially. The thing I adore most flower arranging and now I have time to take on new issues.
