Trace Of Durero’s Spiral DWG Block for AutoCAD

Clear lines to trace Durero’s spiral

Drawing labels, details, and other text information extracted from the CAD file (Translated from Spanish):

Is drawn starting from an isosceles triangle whose smaller angle measures starting from each triangle is constructed another isosceles triangle whose major side coincides with the smaller one of the previous triangle., Is drawn starting from an isosceles triangle whose smaller angle measures starting from each triangle is constructed, The quotients between the major side and the minor side of each triangle tend towards the number of gold., The spiral is constructed by joining by arcs of circumference the consecutive vertices of these triangles., The result is a similar one whose growth factor is the golden number, Durer’s spiral, Another isosceles triangle whose major side coincides with the smaller one of the anterior triangle.

Raw text data extracted from CAD file:

Se traza partiendo de un triángulo isósceles cuyo ángulo menor mide 36°. A partir de cada triángulo se construye otro triángulo isósceles cuyo lado mayor coincide con el menor del triángulo anterior. Se traza partiendo de un triángulo isósceles cuyo ángulo menor mide 36°. A partir de cada triángulo se construye Los cocientes entre el lado mayor y el lado menor de cada triángulo tienden hacia el número de oro. La espiral se construye uniendo mediante arcos de circunferencia los vértices consecutivos de estos triángulos. El resultado es otra similar cuya pulsación, el factor de crecimiento es el número áureo ESPIRAL DE DURERO otro triángulo isósceles cuyo lado mayor coincide con el menor del triángulo anterior.
