![]() ![]() If I go here, Control + T or Command + T, right at the bottom is the layer where this wall is. So you can click here and choose a different layer. In here at the bottom you're gonna find the layer that this element is gonna be. ![]() So ArchiCAD has some standard layers for the elements, so if you don't want them to be on those layers all you have to do when you're adding an element is go to the settings. If we click here on the grid you will see here on the top that we are using the structural grid layer. ![]() So for example when we add those furniture ArchiCAD already put these furniture into the interior furniture layer. ArchiCAD will put the objects on the layers that it thinks it belongs to. And the reason is because you don't really need to. So use it when you only really need it.- Up until now we haven't really chosen any layer for the elements that we are doing. But be aware that this might make your ArchiCAD a little bit slow because it is calculating the subtraction all the time. But remember that this is a live subtraction so if we change the shape of this slab this subtraction will also follow. And if we go back to the 3D, you will see that now the subtraction is done. Get operator and then I will change the operation to subtraction with upward extrusion. Lesson 2 Setting up a new project (15:44) Before we get too carried away we discuss file organisation, project preferences, and layer structure in the second lesson, to set your project up perfectly. And then select the operators which is this lab and these labs. Lesson 1 Introduction to Archicad (15:30) The first lesson gets you started with an understanding of the user interface and basic navigation. I'm going to select the target which is the mesh and get the target. So now we don't have any solid operation happening on this mesh. So we can cancel this solid element operation by clicking here on this X and then clicking on the other X. So if I click here it is saying that we are subtracting from two other elements which I know are true slabs. If I focus here you will notice that we have the solid element operation symbol here. So I'm going to go Control L select all layers put them all on impresso case. I'm going to zoom extend and then let's bring all the layers. So let's press F4 again or F5 if you're in Windows to see the whole house. If I click on the fireplace and then click on this icon it will tell us that we are subtracting another three elements that can be selected from here. But I'm going to undo this because I want to keep it central and notice that now the target and the operators have the symbol here and if we click here it will tell us that we're doing a subtract operation with downwards on the fireplace. If I move a little bit to the side the subtraction will follow us. So now ArchiCAD has performed the operation for us and you will notice that this is a live operation. So I'm going to click on this one and then press execute. Now we can choose some different types of operation like subtraction, subtraction with upward extrusion or subtraction with downward extrusion and this is the one that we actually want. I'm going to click here to cancel the selection and then select the operator and then click on get operator elements. Select them holding shift and then click on get target elements. So the targets will be those three walls. So what we have to do is select the targets and select the operators. I would actually create an empty window on the middle but it's a good example for our exercise. So let's subtract one element from the other. I'm going to do a marquis here on this fireplace area, so I'm going to draw the marquis, press F4 in the MAC or F5 in the Windows and let's say we have this situation here where I have a fireplace object and I have this wall that is in the way. ![]() So we're going to focus on the new operation now. On this tab we have the new operation bar and the maintaining operations. And we can find it in the design tab solid element operation. One very useful tool when you're modeling your project is this solid element operations. ![]()
