Create a surface using an Xref drawing (CAD 2D)

[cjv-consulte]

Hello everyone.

I´m somewhat new to Civil3D and I´m working with a previous drawing made by another person who is not anymore at the company.

The file itself contains a "TIN surface" wich cannot find a way to create it the same way.

It is being taken from another Autocad file (*.dwg) and it´s just inserted as it was an Xref, even tho, it does not show in the Xref tab.

So my question is "How can I create  a surface from another autocad 2D file but it is recognized as an xref?"

* The surface in question is 1084-TOPO (it shows when selected an option called "open source"

* Unlike the other surface "1084 - Topo 2da Entrega" which was created from objects (which are in the same file) , such option does not appear.

Consideration:

I've already seen the method using Data shortcuts, but the surface itself does not show in the data shortcuts, so at this point have no idea how the surface was created at all, but seem to be handy for my needs.

Surface 1084 - Topo 2da Entrega is a Surface created from a point group.

Surface 1084 - Topo is a broken Data Shortcut (Dref). It originally referenced a drawing, 1084-M3-TOPO-ANVANCE 15 NOV 21.dwg.

So it is a Data Shortcut. You'd have to have that drawing and repair the reference.

Yeah I actually have the drawing  and I have precisely updated the reference, my question is "how" I can do that, create a surface from a reference, and not have to copy and paste drawing objects or have a file with points or the likes.

Since most of the time, I´m just provided with a 2D CAD file with triangles or points.

Hi,

You can create a new surface using the already available surface in the drawing (or reference drawings) through surface paste option.

Create a new surface.

Go to edits in definition

Right click edit -- > paste surface --> select the reference surface

Not sure if I understand your question correct, but hopefully this will help you out.

To see if a surface or something else is a data-shortcut it will show the symbol .

When you see this symbol you can open the source drawing and make any edits you like and save it.

You can now synchronize the data-shortcut and the edits will show.

Not sure how to set up a data-shortcut? See the link below.
