Click Annotate tab Labels & Tables panel Add Tables menu Parcel Add Segment.You can close it, as you will not use it again in this exercise. The Add Labels dialog box remains open, in case you want to label more parcels or other objects. When you finish labeling parcels, right-click to end the command.If you wish, zoom in to inspect the labels before you convert them to tags. Press Enter to accept the default Clockwise label direction.Īs you click, labels are placed on each parcel segment. Click the parcel area labels in the following order: 39, 40, 41, 37, 38.In the Add Labels dialog box, click Add.In the Table Tag Numbering dialog box, click Cancel.You will use the Table Tag Renumbering properties later. When you convert the labels to table tags, they will all use a starting number and an increment of 1. For this exercise, accept the default value of 1 for all properties. Notice that there are separate starting number and increment properties for both Table Tag Creation and Table Tag Renumbering. The settings specify the starting number and increment for line, curve, and spiral tags. In the Table Tag Numbering dialog box, examine the settings that are available.Curve Label Style: Parcel Curve Label Style Delta Over Length And Radius.
Line Label Style: Parcel Line Label Style Bearing Over Distance.In the Add Labels dialog box, specify the following parameters:.Click Annotate tab Labels & Tables panel Add Labels menu Parcel Add Parcel Labels.The original “feeder” for this length-6 cycle is the string 10010 (compressed: 11 :2 ), which takes 16 steps to reach the cycle.This exercise uses Labels-4a.dwg with the modifications you made in the previous exercise. We see the same length-2 cycle and terminating state as we saw before. Here’s an example of its behavior:Ĭolumn] Post solved several cases of this problem.īut then he came across the one he described as 0 →00, 1 →1101 with ν=3. If it’s a 0 add a certain block of elements at the end of the string, and if it’s a 1 add another block. He progressively simplified things, until he reached what he called the problem of “tag”. Having converted everything to string transformations, Post needed to have a theory of what such transformations could do. In the summer of 1920 it was all going rather well, and Emil Post as a freshly minted math PhD from Columbia arrived in Princeton to take up a prestigious fellowship. In what seems now like a rather modern idea (with certain similarities to the core structure of the Wolfram Language, and very much like the string multiway systems in our Physics Project), he wanted to represent the logic expressions of Principia Mathematica as strings of characters, and then have possible operations correspond to transformations on these strings. In 1910 Whitehead and Russell had published their monumental Principia Mathematica showing (rather awkwardly) how all sorts of mathematics could be represented in terms of logic. In the early years of the twentieth century it looked as if-if only the right approach could be found-all of mathematics might somehow systematically be solved.
