So on the papers of my teacher it says that I have to double click on the frame and edit the details: 1mm in layout is 1 centimeter in drawing, so I did that but my object is so little and I’m pretty sure that isn’t what he wants to see
I don’t get it??
Your layout units are set to mm. If you draw a line in the layout with length 9.5 you will see that it is about the same length as the top edge of your blue object. In model space, that edge is about 9.5 cm.
All that just means that everything is correct; 1 mm on layout equals 1 cm in model.
As to why the object is so small - I really don’t know. Are you sure the teacher expects to see something else? Perhaps you went wrong some earlier step?
You have your model in CM and your layout in MM. So, your model is roughly 129mm x 129mm. Your paper size is A4 = 297mm x 210mm. 1mm on layout : 1cm in model means you’re downscaling your view 1:10 getting actual scale 1:1. All looks correct.
Maybe your model should be 10 times bigger? Maybe that’s not what teacher meant to ask you?
