Drawing a project with a process more or less top down, every time I insert a new part in an assembly I always wonder whether it is better to leave it fixed or somehow bind the plans to the rest of the geometry and then to go to draw it inside.
this especially in the perspective of future problems of modification of the measures and regeneration of the model and also in terms of lightness of the created model.
Let me give you an example. I have to build the simple model in the image.
1) design a sketch of assemblies as general reference of design 
2) I create the various parts (... why don't I move the sketch over the parts in the order of the feature manager?! bah)
3) I build the column and that attached table, referring the sketches to the general reference sketch.
4) I create the connection part, that kind of flange.
method 1. the mobile rendo, constraint the 3 floors in the position of the edge where the part has to go, open the part in context and start drawing the section on the horizontal plane, always creating references to the general sketch.
method 2. the fixed beam, without constraints and start drawing directly. I open the part in the context of assemblies, I create a floor at the right height,
sketch referenced to the sketch of general plant, and extrusion or sheet that it is.
I hope I explained. Of course, in this example, the two methods are equal, but in a model made of many parts and many reference sketches I would like to aim to keep everything as slim as possible and reduce regeneration operations to the minimum when you change some size. above all I would like to avoid regeneration errors, keeping the structure of the most hierarchical and linear model possible without loops or cross references.
