Divide Tin at regular intervals

BeakHyungi

Hi all,

I am try to make a tool that divides Tin into several parts from top to bottom and show them seperately.

To do that, I planned;
   first, finding the height of top place,
   second, loading height intervals predefined,
   last, dividing Tin into several parts.

Now, I have a problem on dividing task.
Please, let me know how to divide a Tin into several parts at regualr intervals.

Thank you.

Thanks for the PDF. A solution that can be adopted would be to interpolate the fishnet polygon to get Z values from the main TIN so that the polygon boundaries will retain the value from the source TIN with the proper triangulation. You can then select the tile corresponding to a particular TIN and use the Edit TIN tool to add it as a hard clip with z-values.

This can also be automated through Python by using the Make Feature Layer tool to enforce the selection, and referencing the layer name in Edit TIN.

I attached pdf file showing the problem.
You can see the case of Tin with one peak, the methodology is helpful to divide the Tin at regular intervals.
But, in the case of Tin with more than two peaks, the lower part of the pdf, reconstructed Tin is different from the original aspect.

Please, give me your solution.

Thanks.

Suppose that the Tin data has two peaks and one bottom located between two peaks. After converstion of the Tin data to feature class and classification at specific heignt intervals, I constructed individual Tins from the resulting features.
In this case, it is expressed that portion between two peaks which is actually void is filled.

Can you attach a couple of screenshots illustrating the problem? Is the issue that there is a void that should not exist or there is a value fill that should not exist? If it is the latter, then I would advise you include an erase polygon for the area that should be a void.

Hello Beak,

You can use the Copy TIN tool with the output extent argument specified to the desired extent, or export the TIN's elements to feature classes, split them using the methodology I posted in this thread, and construct the individual TINs from the resulting features.

hi beak,

please post the methodology,

thanks in advance

Hi, kduri

I used the methodology you recommended and conversion method seems to be pretty good and easy. But I find another problem.
Suppose that the Tin data has two peaks and one bottom located between two peaks. After converstion of the Tin data to feature class and classification at specific heignt intervals, I constructed individual Tins from the resulting features.

Please, tell me how to solve this problem.

Thank you.

Hi, kduri

Thank you for your answer.
I think your solution can help me make a model, but I cannot find the methodology you said. I think that the link was wrong. Please, post your methodology that you said "the methodology I posed in this thread".

Thank you.
