So, it seems simple in the instruction. Make a rectangle. Draw an “X” through the center. Select the move tool with nothing on the model selected. Click the center of the X. Hold down “up” arrow to lock up/down axis movement and pull up.
Here’s what actually happens to me often (one of several things).
- I am firmly holding the “up” arrow, but movement is not constrained to that axis.
- The point doesn’t move and I see a message such as "constrained to intersect plane."
- Sometimes I have seen the instruction to move the point a little in the desired axis, then press the UP key, but getting that initial movement in the up axis often doesn’t work and wanders off on another axis, so that there is no point now in constraining it to that axis (the point is no longer centered on the plane).
I don’t get it.
