# Modifying

- [Transform](https://help.qonic.com/documentation/qonic-application/modeling/modifying/transform.md): Move, rotate and copy parts freely in any direction, optionally retaining connections with adjacent building elements.  Move and rotate faces freely in any direction.
- [Push/Pull](https://help.qonic.com/documentation/qonic-application/modeling/modifying/push-pull.md): Modify existing geometry by push/pulling its faces
- [Connect](https://help.qonic.com/documentation/qonic-application/modeling/modifying/connect.md): Connect planar building elements such as walls, slabs and roofs.
- [Mirror](https://help.qonic.com/documentation/qonic-application/modeling/modifying/mirror.md): Mirror parts about a mirror plane.
- [Align](https://help.qonic.com/documentation/qonic-application/modeling/modifying/align.md): Align parts, bodies or faces by making selected faces coincide with a target surface.
- [Subtract](https://help.qonic.com/documentation/qonic-application/modeling/modifying/subtract.md): Subtract the geometry of one selection set from another.
- [Union](https://help.qonic.com/documentation/qonic-application/modeling/modifying/union.md): Union the geometry of two or more bodies together in one body.
- [Slice](https://help.qonic.com/documentation/qonic-application/modeling/modifying/slice.md): Slice a selection set by one or more surfaces.
- [Stretch](https://help.qonic.com/documentation/qonic-application/modeling/modifying/stretch.md): Use the manipulator to resize doors and windows.
- [Copy & Pasting Details](https://help.qonic.com/documentation/qonic-application/modeling/modifying/copy-and-pasting-details.md): Copy details from one window or door to other windows or doors.
- [Assembly Editing](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing.md): Manually adjust hierarchical relations between parts by creating and dissolving assemblies, or by adding and removing parts to and from assemblies.
- [Create Assembly](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/create-assembly.md): This tool allows you to create a new assembly by selecting one or more parts that belong together.
- [Add to Assembly](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/add-to-assembly.md): This tool allows you to add new parts to an already existing assembly.
- [Remove from Assemblies](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/remove-from-assemblies.md): This tool allows you to remove one or more parts from their assemblies.
- [Dissolve Assemblies](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/dissolve-assemblies.md): This tool allows you to dissolve the hierarchical relation between two or more parts.
- [Split Products](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/split-products.md): Split a product consisting of multiple bodies into its constituent bodies.
- [Merge Products](https://help.qonic.com/documentation/qonic-application/modeling/modifying/assembly-editing/merge-products.md): Merge multiple existing products into one single product while maintaining separate bodies.
- [Material Layer Editing](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing.md)
- [Split into Layers](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing/split-into-layers.md): Split a wall, slab or roof with an underlying material structure to access the individual layers of materials.
- [Strip to Layer](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing/strip-to-layer.md): Remove all but one material layer of a wall, slab of roof.
- [Replace with Layer](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing/replace-with-layer.md): Apply a new material and change thickness of a wall, slab or roof
- [Add Layer](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing/add-layer.md)
- [Flip Layers](https://help.qonic.com/documentation/qonic-application/modeling/modifying/material-layer-editing/flip-layers.md): Flip the material layer order of a wall, slab or roof.
- [Correcting scattered models](https://help.qonic.com/documentation/qonic-application/modeling/modifying/correcting-scattered-models.md): You can use Qonic to relocate models that have incorrect coordinates.
