Hi,
At the moment I'm using Allegro 17.2. For rotating components I use the iangle function: funckey r iangle 90
Normally it rotates the component perfectly in placementedit mode, but for some designs it doesn't rotate and I get a weird response: Element is already set to this angle.

How can I fix this problem?

From the main menu, take Edit>Rotate, check the Options tab, likely the Rotation Type is not Incremental, probably Absolute, change this to Incremental, go to the canvas and perform a "dummy" rotate to confirm the settings and then Done. The next "Rotate" will use the Incremental setting.

选择文本，拖动器件后右键，选择Rotate，旋转命令，后将旋转方式改为相对。
