Editing a TIN Surface

I have taken over a job and there is a TIN Surface I need to edit. Problem I am having is I don't see any points or breaklines the surface was made from. I have placed block references on my page where I want to add new points to the surface to modify it. Hopefully this makes sense.

 

I have attached the Civil3D file the surfaces are in.

 

Thanks,

Jason

The first thing you need is to apply a Surface Style that has the Points turned on. Either edit the style that is applied to the surface now or create a new one and apply that. Once the surface points are displayed, you will be able to use the surface edit commands like add point, delete point, move point.

That's exactly what I thought, but as you can see by my attached screenshot, I don't see any points referenced....

When you talk about Surface Points ,these are all the points added to the surface, whether COGO Points from Point Groups, or vertices along breaklines and contours, or any location where Civil 3D bases a TIN  line. It doesn't just mean COGO points.

 

The thing you have to do is use a Surface Style that has the Points turned on. See the Display tab of the Surface Style editor.

Ok, that worked, but where did these points come from? Why is there clusters of points? (attachment)

Ok, I just answered my own question. I have discovered the red crosses (points) are from another TIN surface. So my design ground TIN surface was created from another TIN surface called volume june 6. Is this normal?

That's why you would apply to one surface a style that shows the points and apply to the other surface a style that does not.

Ok, that makes sense, but when I highlighted the design surface and made it
show the points, then clicked on the points that showed up, it was just
another surface. So now do I just highlight that surface and make the
points show up and then turn them off in the design surface?

It's all about turning the points on or off in a Surface Style and then applying the style to a surface. If two surfaces use the same style and you edit that style, both surfaces will now display with the changes you made to the style.

Lol...thanks for all your help. I am in way over my head. We are a
Structural Engineering firm and have no business doing Civil work. I used
to do Civil work at Stantec, but not the surfaces and grading.
