When importing DXF files into the Surfaces:

•Vertices from most DXF entities are imported as Nodes

•3D Faces can be imported as Nodes or Elements.

To import surface data:

•Activate the Nodes to import data into.

•Click File > Import > DXF.

•Select an action if data exists in the active Data Grid row:

oRetain Data and append new data

oDelete Data without Undo

oDelete Data with Undo

oLayers

oEntities

•Click OK.

oTo interpolate nodes along DXF lines:

▪Tick the Interpolate Nodes Box

▪Specify the Node Spacing

•3D Faces:

oImport 3D Faces as Nodes or Elements:

▪Nodes: Import the points defining the 3D face as Nodes:

oTo add additional Nodes along the 3D Faces edges:
