How do I move a bunch of tiles at the same time?

I created my level, now I realize I need to make some space and have to move a bunch of tiles. I am pretty sure deleting each tile and re-draw it at the new position is not the right way?

1. Use the Patch Selection Tool into the canvas on the layer: drag the area you want to being included.

2. Select Draw Tool.

3. Move your cursor on the layer onto the Tile Map you're editing. Click Left mouse button to paste the current selection you have. You can also erase bunch of tiles by the Right click.

Check also these so you'll save the time:

construct.net/en/make-games/manuals/construct-3/interface/bars/tilemap-bar/tilemap-brush-editor

construct.net/en/make-games/manuals/construct-3/plugin-reference/tilemap

That was the missing link.

I was using the patch selection tool to draw a tiles from the tilemap, but I for some reason, I couldn't select tiles in the tilemap.

Thank you.
