array modifier

i need to make an array of pv panels as shown on the sketchup image but with blender.

array on the y direction works good but on the x direction it is going perpendicular to the panel the in the global x direction

can someone help me on this?panels_trial_2.blend (444 KB)

this must be accurate since arrays will be very large

You have rotated/scaled your model in Object mode and didn’t applied those transformations, so it throws off many tools calculations (you wouldn’t had this if you did the rotation/scaling in Edit mode).
You can see that by pressing N and noticing that the X/Y/Z scales are not 1.0/1.0/1.0 and the X/Y/Z rotations are not all 0

So still in Object mode, select the object, press CTRL+A -> Rotation&Scale (or click on Object -> Apply -> Rotation&Scale) and it will fix your problem.

oh what a simple solutions, i dont konw how many times i tired to solve it. i feels so silly now. thanks a lot :slight_smile:

Another one:

So I modeled a pv panel and made it into a group and then linked it to another blend file. Now I can’t add a modifier to the linked object

can someone shed some light on the issue?
