compute materials top surface will not show up.

[alexkonieczka]

testing out using link to marked point and volumes i made a 1000' alignment, flat surface at 0, and put a generic lws 10' wide at 0% slope so i would know the real vol in my head to check. i omitted the lws link and then put a marked point at the center of the subassy and then put a linktomarked point and it put the link in ok as shown in the picture. the corridor made a top surface and if i make a vol surface all is correct.

but when i hit the comput materials > earthworks only the eg shows up.

the linktomarked point has top,datum codes by default.

is there some step i am missing?

thanks, alex

Click on the section view and in the contextual ribbon select Sample More Sources.  The "top" surface should be in the pane on the left.  Click on it and Add it to the right side pane.  Make sure you don't have anything that is out of date or that needs to be rebuilt.

thanks. when i did that it looks like put in the corridor before and not the surface and then built the surface later and never sampled it but thought i had it in.
