How to intersect dam slope with target surface?

[Anonymous]

Dear Autodesk people,

I would like to create assembly from a earthfil dam cross-section and run a corridor to create the dam itself. How can i make assembly so that it will daylight to a specified target surface. I could not find a way to do it. There is an example in the following link:

When i follow each step, I am unable to daylight the dam cross-section to the specified target surface.

Thank you

Hello!

I've just made up a few objects and it works just fine for me.

Do you have a screenshot of a cross-section on what you get?

Things to keep in mind:

- you need to have a design profile AND SELECT it when creating the corridor. By default, when using alignment and profile, i think it always selects the first created profile which is more than likely your EG profile. That would draw nawt or jibberish

- looking at the dam subassy (that's the nov 2017 beta, right?) your design profile needs to have space. Core crest thickness + a little, otherwise it jibberish again.

- if your profile for the corridor doesn't run the entire length of the alignment, and you sample outside start<->end of profile stations - you'll get nawt.

These are the first things of the top of my head, if you check those as "DONE" let us know, give us a screenshot or two and we'll see what's what 🙂

Cheers,

Iggy

Dear Iggy,

thanks for your reply and effort. Can you attach your file for me to have a look at it, or can you explain the steps that you have followed?

well, i would if i followed some written steps 🙂

- create (or insert from dref) a surface

- create (or insert from dred) an alignment

- create a surface profile and profile view

- select the profile view and then "profile creation tools". Just make ONE TANGENT profile named TEST for testing purposes that is ABOVE your existing ground

- create assembly with the DAM subassy

- create a corridor with "alignment and profile" , select apropriate ali, profile, assembly, and check the box where is says "set parameters"

- in the next dialog, set your target (existing ground) and interval (i've set it all to 1m)

- PRESTO!

There it is 🙂

(wait..making file for attachment)

There you go!

Cheers,

Iggy
