# CAD Import : Import Options
The data can be imported to the
- Analysis layer – creating elements.
- Design layer – creating members.
# Point
Specifies how AutoCAD points are to be treated in GSA.
# Line
Specifies how AutoCAD lines are to be treated in GSA.
# Arc / Circle / Ellipse
Specifies how AutoCAD arc, circle and ellipse entities are to be treated in GSA. The user provides either a minimum arc angle for splitting the arcs or a number of equal segments.
# Poly Line
Specifies how AutoCAD polylines (LWPolyLine, 2DPolyLine and 3DPolyLine entities) are to be treated in GSA. The user can specify if curve fitting is to be used for curved polylines.
# Polygon Mesh
Specifies how AutoCAD polygon meshes are to be treated in GSA. This allows the user to specify two entities, so for example the mesh may be modelled in GSA as quad elements stiffened by a beam mesh.
# 3D Face / Poly Face Mesh
Specifies how AutoCAD 3D Faces and Poly Face meshes are to be treated in GSA.
