Have you ever encountered a situation in CAD where you wanted to join the insertion points of blocks in a certain order, based on their attributes values?
The GT_CONNECTBLOCKS command in GeoTools can be used for this purpose. Located under GeoTools->Blocks -> Connect Blocks based on Attribute Values, this command displays a dialog box which looks like this:
You select one or more block names that you want to process and specify the name of the attribute tag that should be used. In the Connect points edit box, enter the values of the attributes in the order in which you want them joined. For example, entering explicit values like 10,15,18, 25 will draw a polyline connecting blocks whose attribute values are 10, 15, 18 and 25. Or you can specify a range like 150-158. This would connect blocks with attribute values 150 to 158. You can even construct a multiple Connect points criteria delimited by a comma like 150-158,180-190.
Two special values, Start and End can be specified in the range syntax which denote the first (lowest) attribute value and last (highest) attribute value in the selection. For example, 10-End would connect all attribute values from 10 upto the highest number in the DWG.
The tool shown above works in both AutoCAD and Bricscad versions of GeoTools.
