How not to Power Duplicate by factor


Recommended Posts

I am trying to power duplicate something in Affinity Designer evenly and it just doesn't seem to be working. Whenever I duplicate a layer and then transform the height (anchored to the bottom center) by 2 pixels larger, Each copy seems to transform by some sort of factor exponentially. I'm trying to make each copy two pixels higher than the previous copy. I've tried transforming the height by different amounts and it works properly only when I use ".1", which makes me think that whatever math it is doing cannot factor .1. I've attached a screenshot. If I change the height from 17.6 to 18.6 and then start power duplicating the next number will be 19.7 instead of 19.6 and then the number continues to grow by some sort of factor from there instead of growing by 1 pixel each time. What can I do to remedy this?post-55143-0-00595300-1490490016_thumb.png

AFAIK, that is the way power duplication works, scaling by a proportion, not a specific amount. The only option I've come up with is to set a grid with the interval I want, and manually scale a series of duplicates.

Hi abject39,

 

The topic has already been discussed: https://forum.affinity.serif.com/index.php?/topic/36136-duplicate-or-copy-change-the-empty-space-distance-btw-the-lines-Why /.

 

As gdenby says it must unfortunately be done manually, and this poses a problem for a large number of copies.

I sadly was forced to draw and manually change 240 copies yesterday manually smh. The worst experience I've had in a very long time on a computer. I don't know if Affinity Designer just isn't built to handle GUI task for things other than web. Maybe my case is a bit specific and that's why such a feature hasn't been implemented.

I can understand that but what I don't understand is why if I type in "+=2" in the height it doesn't use the +2 as the appropriate portion for each copy.

I wondered about that, too, but I think it's simply because the program calculates the scale factor by dividing the new height by the old one. So if you start with a height of 20 and set the height of the duplicate to +=2, the factor (20+2)/20 = 1.1 is used for scaling the subsequent duplicates.

Gotcha.
