Obviously line of orange and some other line isn’t imported successfully .

Are all the lines included in the Revit import? If so, maybe the Dwg-nodes from BIMMorph package can help out.

If the bimmorph node doesn’t work you can try a data extraction on the dwg file in autocad to export line point locations to excel and try to rebuild the lines in dynamo from that.

To add to the useful suggestions above, note that RVT files only support planar curves. Any space curves (3 axes) will be flattened to the plane. To prevent this from happening, use a Mass family which supports curves without the need for planes, then place in your RVT.
