![]() (setvar “cmdecho” 0) (setq ss (ssget “x” ‘((-4. Estimated time for completion: 5 minutes. In this practice you will change the (textlayer) routine we created in the previous practice so that it selects both TEXT and MTEXT. For string groups, use wild-card tests, instead of relational tests.See also Creating AutoCAD Command Functions with autolisp This filter-list would select all circles with a radius of 1.0 and also select all lines on layer OBJECT: The number of operands that an expression can enclose depends on the operation. Each Boolean expression must be paired and balanced correctly. You can test groups of objects by creating nested Boolean expressions that are specified in -4 groups, like the relational operators. AutoCAD allows four Boolean operators in filter lists: AND, OR, XOR, and NOT. Unless otherwise specified, an “equal to” test is implied for each item in a filter list. This filter-list would return all the Circle entities in a drawing which have a radius greater than or equal to 1.0 units. To apply a relational test to the value of a numeric group within a filter-list, place a -4 group code along with the operator in a sub-list immediately preceding the group to which you want the test applied.Filter lists for (ssget) can include a variety of options, including relational tests for numerical values and Boolean expressions that look for information such as “this and that,” “this or that,” or “not this and that.”įor numeric groups (integers, reals, points, and vectors) you can use relational test operators.
