# Slice

{% embed url="<https://qonic.wistia.com/medias/1zv19fnu5z>" %}

1. Under the *Modify* icon, click *Slice* or use the <kbd>S</kbd> shortcut
2. Select the parts you want to slice, and press Enter
3. Specify your slicing planes:
   1. Method 1: Slice by Surface
      1. Drop the manipulator on the surface you want to use as slicing plane, or on a surface parallel with it
      2. (optional) Drag the arrowhead to move the slicing plane to the desired location. You can use the input fields to specify precise distance values, or enable Snapping to align with an existing surface or edge in the model
      3. (optional) Hit Ctrl + D to duplicate the slicing plane. The new slicing plane will be automatically offset over the same distance that the previous plane was moved to, but you can still adjust its position manually by dragging the arrowhead
   2. Method 2: Slice by [Chalk Curves](/documentation/qonic-application/modeling/creating/line.md) (only applicable if chalk curves are present on a face of the selection)
      1. Click the chalk curves you want to slice along. This can be a collection of loose curves or a chain of curves.
      2. A preview of the slicing planes based on the selected chalk curves will be shown
4. (optional) Enable the 'Keep as assembly' toggle. This will turn the slice results into Building Element Parts grouped in an assembly which keeps the original product's Name, GUID and other properties.&#x20;
5. Press Enter or click Apply&#x20;

{% hint style="info" %}
If the sliced product is part of a larger assembly, they will be sliced into parts but they will still remain part of the parent product. Use the [Assembly Editing](/documentation/qonic-application/modeling/modifying/assembly-editing.md) tools to manage how the parts relate to each other.&#x20;
