Description:
|
Returns all edges from the entity passed in that are shorter then the specified tolerance. If no tolerance is specified,
SPAresfit is used by default. The third optional argument specifies if detected short edges should be automatically replaced. By default, short edges are not replaced.
|
|
|
entity is an input entity.
|
|
|
tolerance is the specified tolerance for an input entity.
|
|
|
replace is an optional argument specifies short edges should be automatically replaced, if detected.
