建筑沙盘模型中常用模型树工艺及详细步骤 |

我们看到的建筑沙盘模型中有很多物件构成，有水、树木、车子、石头、道路等，那建筑沙盘模型制作中树的制作方法是怎么样的?接下来景文模型公司小编为您解答：
一：制作模型树根
用9-12根长度、直径相同的铁丝，在中部弯曲，然后缠绕在你3或4个手指上(依据树的大小)绞一圈，并再多绕几圈，形成的圈将作为树的根部。然后将圈分成几个圈(每圈包含1或2或3或4根铁丝)，形成分离的圈。现在开始扭曲各个圈以便形成根部。根部需要做成水平，它们将成为树的底部，这个底部将被埋在你的场景地基中，你甚至可以将部分树根做成裸露在草丛中或象种树一样“种”在场景中。将每个独立的圈绞几下，分开并终极形成象根一样的外形。根据你的需要，水平地分开根部，看起来自然些，然后用老虎钳将每个小圈剪开，不必在中部剪开，可以在3点钟或5点钟部位，使每个小圈分开并弄直，成为不同长度的两个树根。
二：模型树干和树枝
为了制造树的上半部分，扭曲上部所有的铁丝几厘米形成树干，直到你所需要做最低树枝的部位停下，在这个部位分出4根铁丝，扭曲这4根铁丝至几厘米长，然后分开成2部分，各自扭曲，做成分枝。留意平衡分枝与第一个分枝的间隔，尽量自然。继续扭曲分枝直到你需要做第二分枝。按照上述办法进行重复操纵。
增加额外树枝
假如你用这个方法制作大树，并使用细的铁丝，那么树看起来有点瘦小，你可以用增加铁丝的办法使树木看起来更茂盛一些。你可以使用同样直径或更细的铁丝，但不要使用很细的铁丝，由于你需要的树将要有足够的强度而不会弯曲的太厉害。假如弹性太大，那么在你往金属丝上涂上石膏或其他材料的以后，树木很轻易损坏。在树干上缠绕额外的金属丝，直到你想增加树枝的部位。可以在上图金属圈中间弯曲成两个圈，再扭曲，做成不同的树枝。象做树根一样剪开成形。你可以重复进行上述操纵步骤，增加更多的铁丝(兰色部分)，直到你的树看起来很棒为止。整棵树完工后，就要修整一下，让树枝看起来更自然些。假如树枝分成2个，大多数情况是水平的，而不是垂直的(请根据你需要制作的树种制作。
三：制作模型树皮
现在你需要覆盖住整个金属丝架子了，避免以后被氧化。在这之前你要确定树的架子看起来如真实的树木那样，树枝和根部要在它们“正确的位置”。很多材料可以用来覆盖。一般的石膏就能满足基本需要了，不要使用太昂贵的或活动性太大的材料，如PU树脂。经过多次的选择，我发现一种贴浴室瓷砖的材料很好用，它是一种象水泥一样的粉状物质，使用时只要倒进水即可，可以调稀一点以便用油漆刷涂刷上树枝。我比较喜欢它而不使用石膏的原因是：a，它具有象胶水一样的粘性物质，可以粘在树枝上而不掉下来，而且不会象石膏那样轻易裂开;b，有稍微的沙质外表，看起来很象树的自然外表
四：增加小枝
你可以使用很多方法增加更细小的树枝，野外的灌木丛或它们的根提供了良好的选择。你可以用胶水粘，也可以用线绑。象扎花束一样把它们扎起来，然后用胶水或线固定在需要的部位，这个固然很辛劳，但是很对结果来说是值得的。直到最后成为一棵漂亮的树木。
五：增加模型树叶
当整个树木完成后，你可以喷上暗灰色(接近玄色)，根据你的需要(在你的园子中观察不同季节的树木)，增加其他颜色，暗绿色会很有效果。树叶不是我的强项，不过我发现一种极好的材料：白桦树的种子。调味原料和药草种子等也是较好的选择。
There are many objects in the building sand table model we see, including water, trees, cars, stones, roads, etc. What's the method of making trees in the building sand table model making? Next, what Jingwen model company compiles to answer for you:
1： Make model tree root
Use 9-12 wires of the same length and diameter, bend them in the middle, and then wrap them around your 3 or 4 fingers (according to the size of the tree) to make a circle, and then wrap them a few more times. The circle will be the root of the tree. Then divide the circle into several circles (each circle contains 1 or 2 or 3 or 4 wires) to form separate circles. Now start twisting the loops to form the root. The roots need to be horizontal, and they will become the bottom of the tree, which will be buried in the foundation of your scene. You can even make part of the roots bare in the grass or "plant" in the scene like planting trees. Twist each independent loop a few times, separate it and finally form a root like shape. According to your needs, split the roots horizontally to make it look more natural. Then cut each small circle with a vice instead of cutting in the middle. You can make each small circle separate and straighten at 3 o'clock or 5 o'clock to become two tree roots of different lengths.
2： Model trunk and branches
In order to make the upper part of the tree, twist all the wires in the upper part for several centimeters to form the trunk until you stop at the place where you need to make the lowest branch. In this place, divide four wires, twist the four wires to several centimeters long, and then divide them into two parts, twist them respectively, and make component branches. Pay attention to balance the distance between the branch and the first branch, and try to be natural. Continue to twist the branch until you need to make a second branch. Repeat the operation according to the above method.
Add extra branches
If you use this method to make a big tree and use thin wire, then the tree looks a little thin. You can use the method of adding wire to make the tree look more prosperous. You can use wire of the same diameter or finer, but do not use very thin wire, because the trees you need will have enough strength to not bend too much. If the elasticity is too big, then after you put gypsum or other materials on the wire, the trees will be easily damaged. Wrap extra wire around the trunk until you want to add more branches. It can be bent into two circles in the middle of the metal circle above, and then twisted into different branches. Cut to shape like a root. You can repeat the above steps and add more wire (blue part) until your tree looks great. When the whole tree is finished, it needs to be trimmed to make the branches look more natural. If the branches are divided into two, most of them are horizontal rather than vertical (please make according to the tree species you need to make).
3： Making model bark
Now you need to cover the entire wire rack to avoid future oxidation. Before you do that, make sure that the tree's shelves look like real trees, and that the branches and roots are in their "right places.". Many materials can be used for covering. General gypsum can meet the basic needs, do not use too expensive or mobile materials, such as PU resin. After many choices, I found that a kind of material for pasting bathroom tiles is very easy to use. It is a kind of powdery material like cement. When using it, just pour water into it, and you can dilute it a little so as to brush the branches with paint brush. The reason why I prefer it to plaster is: A, it has a sticky substance like glue, which can stick to the branch without falling off, and it will not crack as easily as plaster; B, it has a slightly sandy appearance, which looks like the natural appearance of a tree
4： Add twigs
There are many ways you can add smaller branches, wild shrubs or their roots to provide a good choice. You can stick it with glue or you can tie it with wire. It's hard work to tie them up like a bouquet and fix them with glue or thread where they need to be, but it's worth it. Until it finally becomes a beautiful tree.
5： Add model leaves
When the whole tree is finished, you can spray it with dark gray (close to dark color), according to your needs (observe trees in different seasons in your garden), add other colors, dark green will be very effective. Leaves are not my strong point, but I found an excellent material: birch seeds. Seasoning materials and herb seeds are also good choices.
