I'm doing a tutorial and the guy in the video is able to just drag an offset reference plane over, with the intention of dimensioning it later. I can not drag mine, only type in a dimension or use the dimension box arrows. It's not a big deal but I can not find a setting for this in options. I'm using SWX 2018.
OK, now I feel goofy. The trick is to keep holding the LMB after CONTROL+LEFT CLICK to drag the new plane. If you release the LMB you can not go back and try to drag it. I'm still learning simple things even after two years.
