Then select the edges, duplicate and move them outwards, scale them down a bit, separate to make a new object, in that new object in edit mode extrude outwards and then add a solidify modifier. Take care that your normals are facing the right way. If you have mirrors not applied be sure to activate clipping so that the points on the mirror axes don't separate from each others when scaling down. Careful : Rotations in edit mode do not apply a transformation relative to global axes. It's better to rotate in object mode so the local axes are preserved. Once shapes have been modeled out, it can be handy to scale by the normals using ''ALT + S'' Careful when using mirror modifiers, if you move in object mode it moves both sides in the same direction along the given axis because it moves the object center around which the mirror is calculated. If you move in edit mode it moves the selection relative to the given axis effectively copying the move on the mirrored side. When using shapes to cut out mesh in other shapes using the Boolean modifier it is handy to switch the viewport display of the shape being used for the cut into wireframe to see things better. This is done in the Object properties under Viewport Display tab. Don't forget to also toggle it off of the Render in that case. Don't forget to organize your scene into collections that are easy to manage. Unless you are in a workflow where other people will also work on your models in fine detail it is generally a big waste of time to rename each mesh object in your scene. Collections are there to organize your scene into meaningful elements that you can quickly hide/reveal and or select. For pavings its better to work with a plane and solidify modifier than with meshes as you don't have to worry about thickness ; don't forget to apply scales as the thickness will be affected by the changes in scale as you duplicate and randomize these objects. Poke faces is useful for creating a collection of triangles on a big N-gone like circle shape. Applying modifiers is really up to you and depends on if you need to edit the full mesh (in which case apply) to break symmetry When beveling you can press ''CTRL + B'' and then ''V'' to bevel a vertex and create a triangle face where the vertex was. Direct shortcut is ''CTRL + SHIFT + V''. When beveling vertices, use ''J'' to join opposite vertices that were created to re-triangulate the faces and correct the geometry. ===== Scultping ===== === Workflow === Start by remeshing : ''SHIFT + R'' to choose voxel size then ''CTRL + R'' to remesh. A handy shortcut to toggle selection between objects in **Sculpt Mode** is to hover over the object you want to select and then ''ALT + Q'' === Face count === A good figure to start sculpting is anywhere in the tens of thousands of faces for small features and hundreds of thousands for large features. For very detailed sculpting, modelers often go into the tens of millions of faces but this does require an adequate machine (High end CPU & GPU and 64 to 128 GB of RAM). ===== Collection & Links ===== Appending a file to another allows you to bring in any collections from the original file you want to import from. The collection is brought with all it's objects and is more editable. Linking on the other hand imports a collection as a single object. Note that the origin point for that object will be the world origin from the original file, so if the collections are not centered on that world origin it will be offset when you link it. Also note that the link is not dynamic so any change made to the object in the original file will not update in the other project until the first one is linked again. ===== Models ===== ==== Low Poly Cottage ==== Preview coming soon.
