Hi, I wonder why my beam and pegs can't fit together. pls help, thanks.

not sure whether did i update the drivers or not... for the screenshot, i tried with edit mode is also the same, grey background...

may i know ow to change the graphic setting? I tried Ctrl+K but its background is the yellow sandy picture.

i didn't resize them...

I wonder why, last week, I used LDD to design a robot and generated it, the pictures came out was in png files and the background of those pictures is transparent. but today, i tried to design another one, the files are still in png extension, but the background is not transparent but grey... Do I need to reset anything to change back to transparent? Thanks WK
