Every time I render these lines appear, they are like stretching the components
@anjsegarino , thanks for your inquiry - I can see you’ve already set this post to resolved so I reckon this matter is also resolved? May I ask what the culprit was? 
It doesn’t look like glitching.. from the image it looks like actual geometry which gives shadows.. You really see it only when You render (export image from ENS window - Screenshot)? Nothing in the ENS Window itself? Or do You mean by “render” Starting ENScape preview window.?
One guess I can give is that sometimes blocks imported from autocad are very largely scaled or their base point is very far from actual geometry.. or both.. going inside of component, exploding everything in it, setting axes to somewhere in the geometry helps often.. “Scale Definition” plugin helps as well. It resets current scale of component to be the basic scale (not scaled)
