Trying to create divisions/planks of wood in a door I’ve made such as this example that I’m using as ref. I’ve been trying to use lazy mouse and orb cracks (similar to dam standard) but it’s tough to get a really solid division. I have another idea but need to look up more info which is to dynamesh my base and then create cubes, stretch and squash them into plants that I will then intersect/add them into my base. Curious what others think.
Am trying out the dynamesh technique. As you can see here I have inserted a cube, resized it and then cloned it with ctrl+drag 3 more times. Question, I want to now select all 4 and slightly stretch them so that they fit the width of the door. Is this possible? Also, bonus question, I want to mask/select the areas of these planks that are going outside of the frame and delete it. What is a good technique for this? Thanks for any help 
You can temporarily merge them into a single subtool to stretch with transpose/deforms, and then split them back into individual subtools after. I’d keep them all as individual subtools so that you can dynamesh them individually, and help distinguish them from each other.
I discovered that they were all one tool and that I had mask selection applied. So I deselected the mask and was able to edit them as one. Good to know about split/merge though so thanks. Does anyone have any ideas regarding deleting the areas outside of the arch?
The slice brushes should cut right through them

Oh yes I’ve even used that before, forgot all about it. Thanks.
