Offset Alignment Refuses to be created

[Kenth_Kristoffer]

Hello,

I try to create offset aligments on both sides of my center alignment.

After I click ok on the dialog box, it only creates offset on the right side.

It just refuses to create offsets on the leftside regardless of the # of offsets and offset length I used.

Why is this so?

Kenth,

Please post your drawing or a screen shot of your filled-out Create Offset Alignments dialogue box.

As stated a screen shot would help however this can be due to a number of factors.

Alignment geometry.

Does the alignment contain geometry which cant be offset? (ie would overlay due to short radi etc)

How was the alignment created? ie Does this alignment contain curves etc which were drawn using best fit entities. Have you tried reconstructing the alignment entities using regular curves & lines (trace over).

As a check there are two methods to solver the above.

Offset the alignment (as polyline) using regular offset command, this can sometimes highlight where the bad or problem geometry is located.

Land xml out and back into a new drawing. Again sometimes entities are not created as they was highlighting the bad geom.

Aditional required information.

Please see requirements of posts. Civil3d Version inc Spacks, PC Spec etc.

Your post gave me the idea to check for my alignment entities.
It turns out that I have some lines at 0.00m length.
That was what causing the problems.
