Ok, i hope it is ok to give some pointers:
- Hate to say it but i called it
Silvaret guides are good but are more for intermediate (coaster)builders, both your coasters are extremly rough and in real life people would die or at last be injured. My tip scrap the 4m for now. Your pullouts are too tight, your corners and the helix on the woodie is also to tight. As a rule of thumb and don't quote me on that as your life depends on it, you shouldn't transition more than two snaps on any incline/decline (that is not supported by a chainlift), On your first hill, you go to 80° drop, if i guess right and then you go to 0° in one or two pieces, for you pullout your numbers should be more like this: 80° - 72° - 60° -45° - 30° - 22,5° - 11,5° -0°, and this is still a bad pullout, if you use longer pieces the angle of the pullout gets automatically a bit softer so you could do sth like 80° - 45° - 22,5° - 0°, for your corners with 4m pieces you should rarely go over 30° curve and this if you want a tight turn - for the watercoaster: yes you can get away through the shorter trains with tighter turns, but dont over do it, from the layout: lift hill into a triple helix is a bad idea. you want to go on a drop, then with a lift hill you can go to a bit of spaghetti bowl, but don't over do it. Water coaster are more log flume than actual coaster, they mostly don't pull crazy elements.
- for building: you place scenery in front of a grided wall or at least it seems like it. At least for building purposes add it to the building you can remove it later, if you want, but you don't have to deal with the multiselect tool. For every thing i build where i plan on copy diffrent things i either place on grided item or attach them to the nearest building. it is a bit of comfort.
