Sketchup is a compulsory computer-aided course for landscape design students. Together with photoshop and cad, it is called the Three Musketeers of Landscape Design Software. Photoshop and cad are aimed at a wide range of users, while sketch master software is a modeling software specially developed for the characteristics of landscape design, so it is more professional.

abstract

Sketch master is a very simple beginner, but in fact it is a tool for conception and expression, with amazing powerful functions, which is also a problem I often encounter in the process of teaching sketch master course. In the process of learning, students are often very easy to get started, and even can explore modeling by themselves only through the software interface. However, when it comes to actual design, they can't build their own imaginary model through software, or they encounter a series of problems in the process of modeling, such as too large files, sending error reports, and automatically closing, which leads to difficulties in modeling. Below I will summarize the problems often encountered in the teaching process in recent years, in order to improve the efficiency and quality of modeling with sketch masters.

Components and groups

First, the most important thing is that components and groups must be grouped. The most taboo of sketch master modeling is to randomly model, modify and add and subtract the model without systematic grouping. This will lead to the need to modify the model or add materials in the later stage of modeling, and we will be helpless in the face of mixed points, lines and surfaces. This is related to Su's modeling mechanism. If the two models are put together without grouping, then the overlapping points, lines and surfaces will "stick" together and cannot be separated. In this case, I can only advise them to start from a new group, and some even have to re-model. Therefore, in order to facilitate selection, we must establish orderly groups and components in the modeling process.

Classification thought

Secondly, strengthen the concept of classification. Maybe many people will mention hierarchy. Yes, it's a bad habit to completely classify Sue, but the classification is not limited to this. What I want to say is a broader modeling thinking. Many students have encountered a similar situation: CAD facades are all derived from the SU model, and all plants are required to be removed. However, because the plant components are not grouped or unified in a plant layer, we need to hide the plants one by one in order to achieve the ultimate goal. Soviet model sometimes has a large number of buildings and the model is huge and complicated. If you don't classify components with the same attributes, there will be problems: or when you want to hide some components (such as people and flowers), it is incomplete and laborious to find them; Or when you want to replace a certain type of components, you forget some corners. This situation is very troublesome and inevitable, so we must know the types of models at the beginning of modeling and group them in the process of modeling. In fact, it is not required to subdivide each component layer, because SU is not an accurate drawing software like CAD, and there is no need to consider the line type and other issues, and SU has no professional layer management command. However, it is a good habit to classify and group the same type of models as much as possible. In this way, when you want to edit and modify, such components are all in a group.

Draw clean

As we all know, the difference between SU and 3D is that SU supports "surface" drawing. In other words, as long as you like, you can draw points, lines, surfaces and blocks at any part of the model, and draw anything you want to add. This function is the power and convenience of sketch masters and is widely accepted by students. But it is precisely for this reason that we need to form better painting habits: First, strengthen the order of painting. This can avoid some problems that cannot be handled under the SU modeling mechanism. For example, some overlapping surfaces with repeated errors, or some random interlacing of chaotic models, or some endpoints with extremely high overlapping degree that are difficult to capture, may cause some difficult-to-identify situations in the SU system, leading users to fail to achieve the expected purpose. The second is unclean drawing, because adding some blocks at will lead to "unexplained" lines or faces when the final result is produced. Even if you choose to hide them, there will be obvious flaws, which is a serious damage to the effect. In addition, a Soviet model can be said to be composed of lines. The number, density and irregularity of lines are fatal factors that affect the "size" and reading speed of models on computer systems. A clean model is obviously lighter to use than a model with messy lines everywhere, and the more complicated the model, the more this is reflected. Therefore, when making a model, you must be clear-headed and clean.

precision measurement

Arbitrary resizing, lack of accuracy. For example, the conventional size of outdoor stairs is 150mm, which cannot be pushed only by feeling, because the result is probably not an integer; For another example, adding a window to a wall, if we call a window from the model base, we use the scaling tool to scale it casually without numerical calculation, and the final exact value cannot be determined by ourselves; For another example, when a component is placed in the center of the front of a building, we often move it by feeling with mobile tools, and there is no "center" prompt when clicking the mouse. In these cases, we must pay more attention. If our model size is concise and accurate, we can reduce the memory occupied by the model, thus improving the running speed of the software and reducing the error of the model.
