too many tin lines and warbles in my FG surface

[MaryBell1]

I have attached graphics to this question. I have this happening on several projects and I need to resolve this issue. I'm hoping it's just a setting. Its actually a couple of issues but I am thinking they are related.

(1) When I create my coridoor it seems like its creating far too many tin lines. Is there a way to have more control over this. (see image 1)

(2) The FG contours seem to be cruising down the road for a little ways then it appears as if it picks up an EG point then get back on track again.. ( see image 2). you can see the 'bow tie'.

     -my sub assembly checks out (its an inverted crown)
    -if you look at (image 3) you can see my FG looks good on my profile and based on my elev. on my plan it looks like its picking up the EG surface?
    -I have not pasted my EG and FG surfaces.... yet, and I may not.

(3) If you look at (image 4) you can see I have several of these 'warbles' . I can't figure out why it's just not using my sub-assembly straight through. If you look just below the 'bowtie' affect I noticed that it's not daylighting, it just drops off.

Thanks in advance!

Did you use the correct FG Profile for that baseline, in Corridor Properties?

HA.... thanks! Whew, I knew it was something simple I was overlooking. Now that that part is resolved I can see a couple minor issues that I will look at it with fresh eyes tomorrow before I accept this as resoved! Thanks for the quick response.

Now that the target issue is solved you can control the frequency of the corridor. You get TIN line for every corridor sample line

Yes - best practice is to have the assembly frequency fairly wide initially while the design is progressing and then to reduce the frequency when it is time to finalise and compute volumes etc (and the frequency also depends on the EG topography)
