K.2.3 印制增量 按附录 K.2.2. 计算亮、暗平均值之间的反射率阈值，用这一阈值产生出另一个区分亮、 暗的二进制图像。 此印制增量参数，也就是亮暗标记是否能恰当地充满它们的模块边缘的程度，是影响识 读性能的一个重要的过程质量指标。最能标明符号相对于单元名义尺寸的增加量和减少量的 独特的图形结构因符号不同而不同，应该在其符号规范中规定。它们一般是固定的结构或者 是孤立的单元。它们的尺寸 D通过计算二进制数字化图像象素数量来决定。可以独立地对一 个以上的尺寸，例如水平增量和垂直增量，进行规定和检测。对于每一个检测的尺寸规定一 个标称值 DNOM，一个允许的最大值 Dmax和最小值 Dmin。每一个测量值 D 应该归一化到它对应的 名义值和极限值： D'=(D- DNOM)/( Dmax- Dmin) 如果 D> DNOM D'=(D- DNOM)/( DNOM - Dmin) 其他情况 印制增量的等级确定如下： 4.0 (A) 如果 –0.50≤D'≤0.50 3.0 (B) 如果 –0.70≤D'≤0.70 2.0 (C) 如果 –0.85≤D'≤0.85 1.0 (D) 如果 –1.00≤D'≤1.00 0.0 (F) 如果 D'1.00 印制增量测量的目的在于检测组成符号的图形质量，是否偏离名义的尺寸太多，从而影 响比测试条件还差的实际制做条件生产出来的符号的可读性。 K.2.4 轴向不一致性 二维矩阵符号包含由模块组成的数据区，这些模块名义上位于正多边形网格中。参考译 码算法必须能够映象这些模块的中心位置来取得数据。轴向不一致性指的是对映象中心的距 离，即取样点在网格的每一个主轴方向上的间隔的度量和分级。 在每一个多边形的轴向，对相邻取样点的间隔分别整理，然后再计算出沿每一个轴向的 平均间隔 XAVG，轴向不一致性度量了轴与另一轴之间的取样点间隔的差别有多大。即： AN=abs(XAVG-YAVG)/((XAVG+YAVG)/2) 其中 abs()是绝对值函数，如果一个符号有多于两个主轴，那么 AN用由差别最大的两 个平均间隔计算得出。轴向不一致性等级的确定如下： 4.0 (A) 如果 AN≤0.06 3.0 (B) 如果 AN≤0.08

A guide for leveraging SketchUp for any project size, type, or style. New construction or renovation. The revised and updated second edition of The SketchUp Workflow for Architecture offers guidelines for taking SketchUp to the next level in order to incorporate it into every phase of the architectural design process. The text walks through each step of the SketchUp process from the early stages of schematic design and model organization for both renovation and new construction projects to final documentation and shows how to maximize the LayOut toolset for drafting and presentations. Written by a noted expert in the field, the text is filled with tips and techniques to access the power of SketchUp and its related suite of tools. The book presents a flexible workflow method that helps to make common design tasks easier and gives users the information needed to incorporate varying degrees of SketchUp into their design process. Filled with best practices for organizing projects and drafting schematics, this resource also includes suggestions for working with LayOut, an underused but valuable component of SketchUp Pro. In addition, tutorial videos compliment the text and clearly demonstrate more advanced methods. This important text: • Presents intermediate and advanced techniques for architects who want to use SketchUp in all stages of the design process • Includes in-depth explanations on using the LayOut tool set that contains example plans, details, sections, presentations, and other information • Updates the first edition to reflect the changes to SketchUp 2018 and the core functionalities, menus, tools, inferences, arc tools, reporting, and much more • Written by a SketchUp authorized trainer who has an active online platform and extensive connections within the SketchUp community • Contains accompanying tutorial videos that demonstrate some of the more advanced SketchUp tips and tricks Written for professional architects, as well as profe
