Is there a way to create a new window type for the Marvin Skycove?

[myrtsbnye]

Is there a way to create a new window type to add the Marvin Skycove to the program? I've tried editing box windows and can get very close but can't get the top of the box window to look like the skycove. The skycove has a sloped glass top. 

 

Any help would be appreciated.

Is this what you want ?    

You might have to open the Symbol dbx and check "Create 2D Block" to get it to show properly in Plan View.

That looks pretty good. I'll give it a shot.

Thanks Joe
