Hi Karen I don't know how you design BL (computer or hand drawn) but with Adobe Illustrator which I use the circumference of a circular edging is the measurement around the centre of the edging, the outside edge will be slightly bigger and the inside edge/footside will be smaller.
If the strip of lace is, say, 6cm wide to get an exact outside diameter of 150cm you would calculate the first ring as circumference of 144 cm half of 6cm taken off each side of the circle). The second ring will have a circumference of 138cm, the third a circumference 132cm and so on. Circumference is ∏ x diameter = 3.1416 x diameter so the outside ring will be 4.5239 metres in length down the centre. With Illustrator it's a case of drawing one full repeat of the pattern and using that as a pattern brush to draw the circle. The software will stretch or squash slightly to adjust the length required but keeps the width. I don't know how 'Lace RX' or 'Knipling' works. For large circle like that it would be a case of printing out just a few repeats to make a pricking with and then make sure that the right number of repeats is worked. Alternatively, if you are thinking of making a fairly fine lace, such as point ground or fine torchon with a proper footedge you might find that the natural curve which that type of lace gets (without adding extra twists to the outside pair to counteract that curve) will be enough to curve the first few rings - just work a long enough 'straight' edging/insertion of the required length.
