Skillion roof

Hey Guys
Im trying to create a skillion roof with 5 and 7 deg pitches. this roof was drawn in archicad and built on site, but plusspec wont recreate it.
Could you please have a look?
I can email you in the skp file if you need it.

Good day Myles,

Thank you for your enquiry, I have sent across an email to you.
Would you be able to get in contact with me when you get a chance.

Thank you,


Hi Myles,

I had a play around with the roof and I was able to get the roofs to generate but I don’t believe in the result you were after. I believe the reason you may be having trouble creating the roofs is because of one of two things.

  1. The point you started drawing the roof from wasn’t the lowest point in the roof. If you start from a point higher than the lowest point then the skillion roof will not generate.

  2. The lowest points on the entry and lower roof are on angled sides which may be affecting the result you’re after.

What I would recommend to do is to get the roof as close as you possibly can using the Skillion Roof Tool (if it can’t be fully done with the tool) and then to manually edit the roof using SketchUp tools to get your desired result. Please note that any manual edit will be removed if you edit the roof with a PlusSpec tool.

Would you be able to please let me know if this works for you?

Thanks Grant, I will play around with it this morning.
