# Can you erase something in the sagittal plane, without affecting segmentations made in the axial plane?

Hello everyone,

My apologies, probably this has already been addressed previously and I am just not able to find the answer.

I am using Slicer 3D (5.8) with Biomedisa and segmented every 20th slice in the axial plane. I have also made a few sagittal segmentations as a try out, but it did not work well and therefore I want to remove them. However I do not want remove anything from the axial slices. Here is the sagittal plane I want to remove:

If I remove (part of) it, also the axial segments are erased and you do not see the lines continuing:

If it would be possible to only erase the sagittal plane, that would save a lot of work, thank you for your help!

Kind regards,

Severin

I’m not sure if Biomedsia users or developers are active here generally, so you might try looking at their site: [https://biomedisa.info/](https://biomedisa.info/)
