Descriere

Creează o Constrângere prin MEF pentru o intrare geometrică fixă prin blocarea tuturor celor 6 grade libertate a obiectului selectat.

Cum se folosește

1. Click on sau alegeți Model → Mechanical Constraints → Constraint fixed din meniul de sus.
2. Selectați în vederea 3D obiectul căruia să i se aplice constrângerea și care poate fi
   1. vertices (corners)
   2. edges
   3. faces

Limite

Nu puteți amesteca tipuri diferite de obiecte în aceeași constrângere. Utlizați o constrângere fixă pentru fiecare tip e obiect.
