Labeling TIN lines on SURFACE

[RCBmstg007]

Is there away to label (Dynamically) slope arrows and percents on a tin surface (Without Exploding it)? Or is there another medhod to do so?

Thanks

Like this....use labelling

When you have the tin turned on. If you could label slope on the TIN Lines with a feature label or alike.

There is no way to have dynamic labels.

That being said, you can make a copy of the surface, set it to display the triangles, explode it, covert the 3dfaces to regions with the region command, explode the regions, remove the duplicate triangle edges with Overkill and label the resulting 3D lines with a slope label. You''ll have to place the labels one line at a time.

It's a lousy solution but the best I can come up with without custom tools.

Whilst this would do the job (eventually) one wonders if this is what the OP actually requires? The OOTB labelling will work albeit you have to place each label as well but there ia also the slope range analysis tool to consider.

It would be useful to know from the OP what they are ultimately trying to achieve.

The Engineer was asking for if this was possible. I did suggest the method about exploding the TIN to Feature Lines and then Adding Slope Labels.

I believe he is trying to get a cross slope on the tin for either ADA or something that is even flatter.

Thanks for the clarification - I still think using slope labels under Annotation is the best bet as you can choose the two points of interest and these labels will remain dynamic if your surface changes whereas the other suggestions will require you to do the whole explode/region thing again.

In cases where you only need to evaluate ADA requirements I think you'd be better off just applying slope labels where needed vs. trying to label the entire TIN. If you are needing to identify potential routes you could apply a slope theme to the TIN and then evaluate the areas that fall within the acceptable range in more detail.

If you find there are lots of TIN labels needed you could explod the TIN down to generic 3D lines and make use of Map or generic Autocad annotation tools to label the lines by selection set vs. picking them one at a time with the C3D label tool.

If I were trying to evaluate individual ADA routs. I'd define them with Featurelines with their elevations from the Surface. Then label the slope on them. Not dynamic to the Surface but you could apply the new Surface elevations if the Surface was updated.

Not what the OP asked. But I like to give options.
