You want to experiment things. Create this support without knowing exactly where it will be fixed. After you finish you part desing, you will start to be concerned about creating the supoort that is missing. Based on that, you design. Just remember that you can use a lot of different things as a contextual reference planes, surfaces, notes. Top down: You have an existing part or assembly.
Top-down and bottom-up design
Difference between Top-down and Bottom-up Approach (with Comparison Chart) - Tech Differences
You can create assemblies using bottom-up design, top-down design, or a combination of both methods. Bottom-up design is the traditional method. You first design and model parts, then insert them into an assembly and use mates to position the parts. To change the parts, you must edit them individually. These changes are then seen in the assembly. Bottom-up design is the preferred technique for previously constructed, off-the-shelf parts, or standard components like hardware, pulleys, motors, etc.

They control the operations of many machines in our factories, they allow us to communicate with people on the other side of the world, and we can even play games like Chess and Go with the best in the world. Is it any wonder that we are constantly looking for ways to efficiently and effectively program them?
The algorithms are designed using two approaches that are the top-down and bottom-up approach. In the top-down approach, the complex module is divided into submodules. On the other hand, bottom-up approach begins with elementary modules and then combine them further. The prior purpose of an algorithm is to operate the data comprised in the data structure.
