import gds in momentum

I alwasy met off-grid problem when I import the virtuso file to ads momnetum
in gds format. How to avoid this?
Any setup do I need to care when I perform the "stream out" in cadence?
Thanks,

Momentum layout tool isn't as good as Virtuso. If you have non 90 deg bend, off-grid is hard to avoid.

No.. there is no setup,for this.
But i'm sure that you draw 45 degree lines by using "line" and that creates off-grid problem. Instead, use multiline ( or polyline) to connect the straight lines with 45 degree miters as we do.;.

It will solve your problem...

I import a layout from tsmc inductor from virtuso to momentum. Do you mean
I need to make the metal trance intro polygon? the polyline is in momentum or virtuso?
thanks,
