Descripción
La utilidad Validar croquis puede utilizarse para analizar y reparar un croquis que ya no es editable o que tiene restricciones no válidas, o para añadir las restricciones coincidentes que faltan a un croquis creado a partir de geometría importada, como los archivos DXF. También puede ser útil para localizar una coincidencia que falta en un boceto nativo que genera un error de "no se puede validar la cara rota" al intentar aplicar una función de DiseñoPieza.

Utilización
- This tool cannot be used while a sketch is in edit mode. To finish edit mode see Sketcher LeaveSketch.
- Select a sketch.
- There are several ways to invoke the tool:
- Press the
Validate Sketch button. - Select the Sketch → Validate Sketch option from the menu.
- Press the
- The Sketch Validation task panel opens. See Options for more information.
- Press the Close button to finish.
Opciones
Coincidencias Falta
Finds out missing coincidences for overlapping vertices, and adds them. Press the Find button; a pop up dialog will appear to report how many missing coincidences were found; they will be shown in the 3D View as yellow crosses. Press OK to close the dialog, then press the Fix button to add the missing coincidences.
If necessary, define a different tolerance value in the drop-down field.
Press Highlight Troublesome Vertices to highlight vertexes that are outside this tolerance.
This tolerance is also used by the Find/Fix process.
Leave the "Ignore construction geometry" checkbox checked to disregard construction geometry in the analysis.
Restricciones no válidas
Checks for malformed constraints.
For example, if there is a Circle-Line-Tangent constraint, but it references two lines, it is considered invalid.
(This sometimes happens due to the Topological naming problem, i.e. the external geometry changes type).
It also does other checks, such as for empty links.
Geometría degenerada
Degenerated geometry can result from solver actions in a sketch.
For instance, if a line is forced to shorten to become almost a point.
Other examples: a zero length line or zero radius circle/arc.
Geometría externa invertida
Reversed external geometry can happen because the handling of reversed geometry was changed around revision 0.15.
This process might be helpful if sketches with external-geometry fail to solve because of these changes.
Bloqueo de la orientación de las restricciones
Tangent and perpendicular constraints are implemented (via-point).
Internally they work by constraining the angle between tangent vectors. With tangent constraint for example, the angle can be 0 or 180 degrees (co-directed or opposed vectors). The actual angle is remembered in the constraint data ("constraint orientation is locked"), it guards against flipping. But the angle can be erased ("constraint orientation unlock") or updated; these tools do exactly that.
The locking mechanism typically works well and this tool should not be needed. It should only used after making a backup of the open document.
