catlover Posted October 13, 2022 Share Posted October 13, 2022 Please see example attachment: I have to duplicate the small circles along the entire path formed by the middle circle. Turn on "enable transform origin" to see the common midpoint of the circles. Can't figure out how to do this by power duplicating. Any help is vastly appreciated, thanks !

GarryP Posted October 13, 2022 Share Posted October 13, 2022 Find the circumference of the middle circle (C=pi*diameter) [diameter is the circle width in this case]. Divide that number by the diameter of the small circle (D=C/smalld). Then divide 360 by that number (R = 360/D). Select the small circle. Enable Transform Origin. Move the Transform Origin to the centre of the middle circle. Duplicate the layer. Enter the R value you calculated earlier into the R field of the Transform Panel. Duplicate, Duplicate, etc. etc. You might need to tweak the rotation value if it doesn’t come out quite right because of rounding errors.

v_kyr Posted October 13, 2022 Share Posted October 13, 2022 Or alternatively try out text on path, but instead of inserting artistic text there (on one selected bigger lead/guide circles) paste in your little circle repeatedly.

v_kyr Posted October 13, 2022 Share Posted October 13, 2022 Or probably the most flexible, let Python instead do the work of distributing smaller circles around a bigger circle (where you can define the radi for the big and small circles and the number of small circles) and then save the whole as in ADe reusable SVG code. - A little Python script ... import numpy as np import matplotlib.pyplot as plt num_circ = 7 rad_large = 7 rad_small = 4 thetas = np.linspace(0, 2 * np.pi, num_circ, endpoint=False) fig, ax = plt.subplots() ax.add_patch(plt.Circle((0, 0), rad_large, fc='none', ec='navy')) for theta in thetas: ax.add_patch(plt.Circle((rad_large * np.cos(theta), rad_large * np.sin(theta),), rad_small, fc='none', ec='crimson')) ax.autoscale_view() # calculate the limits for the x and y axis ax.set_aspect('equal') # show circles as circles plt.savefig("myimg.svg") # save as SVG plt.show() myimg.svg myimg.afdesign circles.py (the Python script) SureWeb 1 Quote ☛ Affinity Designer 1.10.8 ◆ Affinity Photo 1.10.8 ◆ Affinity Publisher 1.10.8 ◆ OSX El Capitan ☛ Affinity V2.3 apps ◆ MacOS Sonoma 14.2 ◆ iPad OS 17.2 Link to comment Share on other sites More sharing options...

I think what you are wanting to do is get 26 circles of 35 mm distributed. Be aware that in this case it is possible to do so, however if you wanted a different size it may not be possible. Geometry. Divide the 360 degrees by 26 and that should do it. In future you'll need to remember that only some sizes of the smaller circle will fit into a pair of inner and outer circles.

If that is meant, that's easy to do with the above script slightly adapted too then (...here the python SVG result is placed on the OP's initial A4 portrait page). circles_py_v_kyr.afdesign Quote ☛ Affinity Designer 1.10.8 ◆ Affinity Photo 1.10.8 ◆ Affinity Publisher 1.10.8 ◆ OSX El Capitan ☛ Affinity V2.3 apps ◆ MacOS Sonoma 14.2 ◆ iPad OS 17.2 Link to comment Share on other sites More sharing options...
