Corridor Curve Irregularity

[aniruddh_ab]

I'm trying to curve the Trench "Corridor" in image 1 but the corridor is getting curved not as per the design/layout.

But in the image 2 the Trench "Corridor" is getting curved exactly as per the design.

Why is it happening? What is making corridor result differently?

And

What is the solution? 

[RobertEVs]

Bend angles too tight? Can you put a small radius in your alignment? 

[aniruddh_ab]

I'm using feature lines instead of alignment

[aniruddh_ab]

Also, I cannot change the layout design.
I have to lay/build the trench on the layout design

[RobertEVs]

Then try and make a region in the corners and set the frequency very tight for both horizontal and vertical baselines. Or set the entire corridor down to a .25 frequency before making regions and see if that helps. If it does then isolate the tight frequencies to regions in just the corners

[RobertEVs]

You can see the links have an impossible task of making the corner. A small featureline fillet may necessary. Someone else may know a very easy fix but this is all I can offer

I'll wager that corridor 1 has a tiny curve at each of those bends, and a corridor station at the midpoint of the curves.

[Joe-Bouza]

Ill double down on that. and a tiny MO for curve frequency

[aniruddh_ab]

I tried adding a fillet curve and added corridor station at the midpoint. It resulted in unclean trench corridor.

Any suggestions to get clean trench corridor?

[sboon]

Go back and look at your original screenshots again.  In 2 the spacing of the corridor leaves enough room so that there are no overlapping sections at the corner.

[aniruddh_ab]

I know that there is enough spacing given in the corridor (image 2).

As I have already mentioned earlier, I cannot change the layout design. 

Is there any way that I can have a clean trench corridor on the existing layout design?

Hello,

• For this type of geometry when your trench is very wide to compare your radiuses corridor is not effective with bends you can split you corridor into different regions and at the places of bends put Grading objects .
• use offset feature lines and grading tools all along the section, instead of corridor modeling workflow to get clear bends for your trench
• If you are confident that you want to use corridor and don't want to use grading you have to add curves with necessary radiuses for proper corridor geometry, on you feature lines and you have to sacrifice your angles.

Hi @aniruddh_ab,

Thanks for posting. Great suggestions and tips by @RobertEVs, @sboon, @Joe-Bouza & @Beka_Tchigladze. 

To add, have you tried using the clear corridor bowties feature? 

If you prefer manual approach, check out these various forum posts:

Split out this region (between thick yellow lines). Add a couple (small yellow) plines. Target them for width within this region. See if that works

 

[aniruddh_ab]

I tried this method (by adding "targets" to the subassemblies and targeting it to the trench side lines) but still the trench corridor is not coming out clean.

Hello, there are minimum 3 way above to solve this problem in the comments. Could

you reread them one more time and try to fit on your case? There is not easy one click way to model this type of geometry with corridor

[aniruddh_ab · Accepted solution]

Found a solution which sort of works at the moment for such a corridor design,

The bend area [within yellow lines] where lines/alignment/feature line meet at the curve/bend point are supposed to be straight [shown as red lines] (should not have any curve).

Before and beyond the "bend area" lines/alignment/featureline can be curved [shown in sky blue color].
