    关于建筑模型中弧面制作的常见方法
    2019-5-7 13:17:49 来源:http://www.jnsymx.com
    很多同学有问弧面的模型制作方法,关于选材,具体制作过程,注意事项等。东营模型公司在这里告诉大家弧面模型基本都是在犀牛中完成设计的,若要将其等比例制作出来,用平整的材料来实现弧面的效果,要么板材弯曲,要么块状材料切割,要么直接3D打印。
    Many students have asked about the method of making the model of arc surface, about the selection of materials, the specific production process, matters needing attention, etc. Dongying Model Company here tells you that the Globoidal model is basically designed in rhinoceros. If you want to make it in equal proportion, you can use flat material to achieve the effect of the globoidal surface, either the plate is bent, or the block material is cut, or direct 3D printing.
    1.泡沫板切割
    1. foam board cutting
    泡沫板搭配电热丝切割机除了可以制作横平竖直全是直线的体块外,也是可以进行弧线,曲面制作的。
    Foam plate and electric wire cutting machine can not only make horizontal, vertical, straight line blocks, but also make arc and curved surfaces.
    进行复杂形状的泡沫切割时,需要打印出所需模型的轮廓,一式两份。将其上下对面贴于泡沫板两面,边缘区域需要额外注意粘贴牢固(这里推荐3M喷胶)。电热丝会被上下两面的纸张所限制,使得切出的体块非常完整光滑。
    For complex shape foam cutting, it is necessary to print out the outline of the required model in two copies. Attach the upper and lower sides to the two sides of the foam board. The edge area needs extra attention to stick firmly. (recommend 3M spray glue) here. The wire is limited by the paper on both sides, making the cut block very complete and smooth.
    当上下两层有差异,则能用以制作弧面效果。
    When the upper and lower layers are different, they can be used to produce arc effect.
    2.板材弯曲

    2. Sheet bending

    将所需制作的面 在犀牛中使用UnrollSrf命令,可以精确地将其展开为二维面,然后采用激光切割或者打印出相应比例图纸对着裁剪即可得到。所选板材需要是容易弯曲的,例如白卡,1mmpvc板等。若是弯曲幅度不大,则稍厚的板材也可以被使用。
    By using UnrollSrf commands in rhinoceros, the required facets can be accurately expanded into two-dimensional facets, which can be obtained by laser cutting or printing out the corresponding scale drawings. The selected sheets need to be easy to bend, such as white cards, 1mm PVC boards, etc. If the bending range is not large, a slightly thicker plate can also be used.
    3.特殊材料的弯曲
    3. Bending of Special Materials

    木条,abs管等材料。这些材料的弯曲,需要改变其物质状态,木条在水中充分泡过后容易弯曲,abs管在加热后容易弯曲(可用大功率吹风机-热风档)用钉子等工具辅助固定曲面,等材料稳定后,即可成型。

    Wood strips, pipes and other materials. The bending of these materials needs to change their material state. The wood strips are easy to bend after fully soaking in water. The pipes are easy to bend after heating (using high-power blower-hot air shield) and fix the surface with nails and other tools. When the materials are stable, they can be formed.
