I have a dozen speakers in an arc inserted as a circular array that are aligned horizontally around a center point. I want most of the speakers to point directly down; so as an example a speaker has a horizontal rotation of 36 degrees (so that the speaker's long axis is perpendicular to the center point) and a vertical rotation of -90 degrees (so it points straight down). When I change the vertical angle or the rotation angle the speaker doesn't rotate about the horizontal axis of the speaker, it rotates in other undesired directions.

When I was working on the initial layout, I just sort of pointed stuff and shifted things around so that they looked weird but were acoustically acceptable. This version is going to the Owner and I would strongly prefer not sending them an ugly model.

Thanks,

Hi Lindsay,

may you can send your EASE project to the AFMG support (support@afmg.eu).
That would be helpful to better understand the issue you reported.

Best Regards

I finally figured it out. By trial and error I determined which combination of horizontal, vertical and rotation would allow me to get the required aiming.

I realize that this is not a typical speaker arrangement but it was still way harder to get right than I felt it should be. Hopefully the next version will simplify this.

To clarify, I was trying to rotate a speaker about it's own axis, not the drawing axis. I had already positioned and rotated the speakers, I just wanted to change the down angle without changing anything else. This comes up a lot for me when I'm aiming speakers, especially speakers flanking a stage. Is there a work around that I haven't found yet?

Thanks,
