>>6866927No one answer really.
I keep things studded or smooth depending on both what i'm going for aesthetically and their functionally.
I like to build cars, so some level of smooth curvature and 'aerodynamic feel' i try to pursue.
I like studs so i can securely place props, furniture and figures and stuff. Rough studded areas work great for like dirt, sand or grass. It can also give the illusion of a slightly raised surfaces or curvature. The roofs of my cars are generally studded in the middle four rows of studs. Both because it makes the roof look less flat and because i like attaching things to the roofs of my cars.
The reason i tiled and jumpered off my sidewalks (despite liking studs for placing things) is that i like to have some organic extra posing options. When you place a figure on one studs and can alternate between what leg it connects to, and you can place it diagonally, it creates a lot of options for dynamic posing.
So in the end i work way more smooth than i used to, but have no hard rules or anything. I like it when i place older sets and builds next to my newer ones and the studded and more simple techniques almost make classic space rovers and such look like 'vintage design' in-universe.
>>6866939The upcoming cmf policeofficer has a box of a different set i believe. A policecar that had a two-wide windscreen and a minifigure. I forgot the number and set name.
>>6866974I think i had a trike very similar to the green one. I really like bikes, but it always bothered me i didn't had figures to ride them. My scuba-slizer didn't really fit.
I still stick to the old-style minifigure motorcycleframe. Not only do they scale really well, i have a trauma/extra appreciation for them since i accidentally flushed a police motorcyle down the toilet of a restaurant when i was little.
