To get the x, y, and z value we can use car, cadr, and caddr.Ĭar will pick the first value from the list.

Now after you run it once, type !p to see the p value. We haven’t define p and textloc as local variables, so the value should be still stored even after we run the program. See how many decimal numbers it has? Getting Value from The List We can’t control the text appearance, the label will be shown similar like below. The program can be used, but the result is not good enough. Try to use it first if you want to know how mleader works, pay attention on each step what you should do. What if you don’t want to use leader, but would like to use Multileader? Simple, use this line: This line below will do what is described above. Leader will ask for another input for the next line.In AutoLISP program we can use point coordinate we get from user. To simulate in AutoLISP, we simply use “”. If we only want one segment, we can press. It will ask for another point for the leader.We are going to use text location (textloc variable) as second point. The first point will be the point we label. After we activate leader tool, we need to place first point.In visual LISP editor, you can copy or type it (I suggest you to type it for your exercise) then click load active edit window.Īfter you load it, type cnlabel to activate the tool. (command '_leader' p textloc '' p '') activate label tool and use the input Pick Text Location')) asking user to click text location Pick Point to Label: ')) asking user to click point to label and save it So you should already familiar with this code: We already learned how to ask for user input for a point. It will require us to define two points: point to label, and where we want to place the label. We are going to use leader tool to label it. See the program and try it first if you want. We are going to create a program to place coordinate label for a point automatically. We have learned how to use mathematic equation in AutoLISP to calculate a value. This time we are going to use lists and strings. In this exercise, we will continue our AutoLISP tutorial.
