Hi @kmarkopouliotis
One way you can do it is via the function segment_get_point()

// Get details of the first point of the first segment entity tp = entity('toolpath', 'mytp') int segment_id = 0 int point_id = 0 object ptdata = segment_get_point(tp, segment_id, point_id) // Round the z coord to 2 decimal places, to match the output in the // Reorder form. ptdata is a map, one of whose elements is an array // with the xyz of the point. real z_coord = ptdata['position'][2] real rounded_z = round(z_coord, 2)

Another way is to obtain values directly from the form:

// Get the string in the first row and second column of the // Toolpath Reorder form, which should be raised before values // are obtained (the indices start from zero). FORM TPLIST string entry = list_cell_value('TPList.TPListView', 0, 1) // This returns a string in the form "10, 20, 30". So, split the // string. string delim = ',' string list coords = tokens(entry, delim) // This gives a list, whose 3rd element is the z-coord real zval = coords[2] print par $zval

Thank you,

i'm trying to write an expression in order to have a quick observation of the toolpath's information....

In case you haven't considered it already, could you wrap either of those methods in a function and arrange to call that, e.g. something like:

FUNCTION first_segment_z(ENTITY tp, OUTPUT REAL zcoord)
