I am very frustrated. I have watched about 20 YouTube tutorials on Sketchup. I’m using Make 2017 on a Mac. Some times everything is fine, however most of the times I start a project I am unable to even make a rectangle with the correct dimensions.
Now for example I am trying to make one with the dimensions 148x19 millimeters. I have Model Info set to millimeter. If I draw the shape and then enter the numbers, the rectangle usually pops to something else that isn’t evn close. Some random shape. No matter what axis. I can see the dimensions entered correctly down in the corner. But the actual shape can be 20 times longer. If I draw a manual rectangle and carefully pull it to the correct dimensions and then measure it with the tape measure, one size will always be 148.2 millimeters instead of 148.
Restarting or using a different template doesn’t help. Have I envoked some bizarre custom setting? The day before yesterday it was like this. Then yesterday I had some problems and then after many attempts it suddenly worked. I continued to draw a nice woodworking dovetail joint. Today again I am unable to make a basic rectangle.
