Hello,

in this drawing you’re seeing the top left corner of a trapezoid that is placed inside a box.  
 ![Bildschirmfoto 2021-05-28 um 12.13.41](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/5/50acd8ca0f207126f42d5c936a54297f14f4ba69.png)  
I would like to align the upper line of the trapezoid with the above horizontal line. In oder to do this I click on the white circle that appears when hovering the mouse over it,  
then select the arrow that is pointing upwards and finally insert a value. I do succeed to align these two lines however, when I do that the entire trapezoid is moving upwards so that the bottom line disconnects from where I want it to be. (Please see screenshot in next post)

So my questions is, what do I need to do to avoid the entire trapezoid from moving upwards? How can I align both the top and the bottom line of the trapezoid to the adjacent lines?

Thanks in advance for your help, Zumen
