First, hand-painted, perspective, practice more and draw more after mastering the perspective principle.
Second, the software, PHOTOSHOP CAD 3DMAX, these three softwares should be able to. CAD is very important, and dozens of drawings contained in scheme drawings and construction drawings should be drawn with CAD.
3D is mainly used to make aerial view of landscape and post-PS rendering. Of course, it is not too much to meet another SKETCHUP.
Third, the landscape theory, you can find more books to read.
4. Engineering drawings: scheme drawings and construction drawings.
The following are several types of drawings involved in the design of scheme and construction drawing (incomplete, just to give you an idea).
Scheme drawings: more than ten types of drawings, such as current topographic map, axis analysis map, functional zoning map, traffic analysis map, CAD general plan, factory intention map, etc.
More construction drawings: construction layout, vertical design, road design, plant planting design general plan, water supply and drainage construction design, pavement engineering design, landscape architecture design and so on.
Single construction drawing includes 10 kinds of line drawings, such as CAD total horizontal line drawing, landscape node line drawing, garden road route drawing, water supply and drainage line drawing, etc. There are many construction drawings, so I won't list them one by one.
5. Plants: A qualified landscape designer should master at least 300-400 kinds of common plants, including their growth habits, cultivation and maintenance, and how to use them in your design.
The above is just a general idea, and the scope of landscape design specialty is still relatively wide. If you want to teach yourself, you may have wasted your time and learned nothing.
It is better to choose a good training school. A good training school will enable you to master the professional knowledge of landscape design comprehensively and systematically in just a few months. But only if you study hard yourself.
But then again, there are really not many training schools that can teach all the courses of landscape design, so you must be careful when choosing! I heard that Qisheng Landscape Design Training School is OK. Several colleagues in the company are from that school. I borrowed several colleagues' reading notes and found the course comprehensive and systematic.
These are all my personal opinions, I hope I can help you!
