Thank you so much Marcel for replying to my query.
By the node you have suggested it is giving me the local co-ordinates of element, I want the vector of the edge of the surface, is there any node for that.
Let me explain to you what I am trying to do is, extracting the edges of surface and translating them by certain distance and using the edge geometry as input giving the dimension to the element.
by my script I am able to successfully translate vertical edges with normal to the edge as direction input
but in case of horizontal edges translation of curve is occurring along the length of beam(As shown in the screenshot)…I want to translate it in the plane of surface…Please help me out. If there is any other method for dimensioning please let me know.
Thanking you in advance.
