Requisito mínimo para un croquis
La creación de un cuerpo en el espacio de trabajo DiseñoPieza ya es posible y sólo con la ayuda de una curva cerrada (perfil). La determinación completa de todas sus dimensiones y propiedades (totalmente restringida) aún no es necesaria.
Que una curva cerrada está presente, no es evidente y no es reconocible. Cuando se conecta un arco circular a una línea recta, por ejemplo, los dos puntos finales se crean sólo uno sobre el otro. Debe utilizar el Coincidente para hacer un solo punto que realmente conecte la línea y el arco.
Un boceto sencillo. Izquierda: Curva sólo en cuatro lugares (rojo, restricciones automáticas al dibujar con Polilínea) cerrada. Medio: Advertencia - ... cara rota (curva rota). Derecha: Curva cerrada en los cuatro lugares restantes (verde)
Sin embargo, el trabajo paramétrico consistente significa que el croquis está completamente determinado.
Definir un croquis por completo
Incluso un croquis relativamente sencillo puede contener docenas de indeterminaciones (indicadas en la vista combinada como un número de "grados de libertad"). Eliminarlas juntas al final es una tarea relativamente confusa.
A simple sketch; completely determined by 25 constraints, of which only 5 are dimension constraints.
This work is clearer and simpler if one immediately eliminates the "freedoms" of each added geometric element, i. this dimensions (that is, values for dimensions and placements). The provisional completeness is reached if all lines are displayed in green.
If one waits until the end of the drawing to determine, one finds remaining "freedoms" by touching the points and lines with the mouse pointer and determining where they are not yet fixed. When complete, the entire drawing is displayed in green.
If you accidentally create an "overmodulation", a warning appears in the combo-view asking you to undo the corresponding actions (constraints).
