Stacking duplicate features using Duplicate Vertical / Array editing tools

Stephanie-Ingraldi — Wed, 14 Jan 2026 20:19:38 GMT

I am attempting to stack polygon features by creating multiple duplicates at once. I thought I could achieve this by using the Duplicate Vertical or Array editing tools and setting any of the offsets to zero feet, but when I hit Duplicate/Array, no additional features get created. It only works if the offset is greater than zero, but I need my features to stack exactly on top of each other with no vertical or lateral offset. Is this intentional or a bug? If it is intentional, meaning it's not possible to set the offset to 0 feet, then there should be some warning or the execute button should be grayed out.

I might be misreading your requirements but would selecting the polygons you want to duplicate, copying them out to a new dataset, and then repeatedly appending the copies back to the source solve your problem?

is it this tool?

Duplicate 3D features vertically—ArcGIS Pro | Documentation

and if so, it is offsetting vertically so you need to offset by a finite amount, and the x,y plane remains intact, only the z changes.

If you have a proposal to disable the tool if z is set to 0, then you can create an "Idea"

@Stephanie-Ingraldi The Duplicate Vertical and Array tool are expecting something other than an offset of 0. We wanted to prevent cases of unwanted duplicates. As far as getting duplicates, I assume Copy > Paste isn't a desired workflow for you?

For what it's worth, you can click Paste as many times as you need. Maybe you need hundreds of duplicates?

Hi Scott,

Yes, copy/paste is not desired since I need to make many duplicates at once multiple times over (I am stacking parcel data onto condo building footprints. I am aware of the one-to-many join workflow, but this doesn't work when I need to stack multiple buildings within one parcel). Right now, I am just using Duplicate Row, but it would be more efficient to create all duplicates at once.

Thanks for the additional context and feedback. The development team will consider enhancing existing tools to accommodate your workflow in a future release.
