Roof too complex to compute

[cwailes]

Everyone,

I am trying to model this roof and I am getting the "Roof is too complex to computer" error and no matter how much I edit it, I can't get it to draw it. Any help is greatly appreciated. I have included the VW file as well as a screen shot.

Can you post a VW2008 version file so I can play with it?

The roof tool is an anaemic plugin that often fails trying to model even simple roof forms, it's not surprising that it's failing on that polygon. It's still useful however, try separating the base poly into 2 or 3 simpler forms the roof tool can handle then convert them to roof faces for editing into the roof you want. The aspects causing it to fail or crash VW are not always what you'd expect, long wings off of a main body (like the one on the rear right of your polygon) are often problematic.

I'm not sure how you want the curved section to connect, either as a separate flat roof or with a valley against the next section, but it's also likely a problem as it is.

M5d is right.

If you run the radius part separately from the rest of the polyline it works.

You will probably get more useful results creating roof faces.

Wow! This should be no problem.

Seems like VW needs some "repairs" in its roof tool.

Should not have to go through this gentlemen.

That roof line is not that complex.

imho

Is this what you are after?

See images

I did this in the other CAD software Iuse.

Imported your .png file.

Traced over with wall tool

Used roof tool > Auto roof

Took me longer to trace image for walls than to create roof.

Like I said earlier, this is not that complex of a roof.

Taoist that is pretty much what I was trying to do. If you don't mind me asking what was the other software you used to create it?

The problem is the reentrant corner where the round roof connects to the straight roof on the lefty hand side. The Vectorworks Roof routine does not deal well with with even simple reentrants so its not surprising that it doesn't deal with this one.

[taoist]

Could this be done using roof plane tool?

As I do not have version 2011, is there a roof tool that allows you to "trace" a roof area to apply the roof to?

Can you add a roof to an existing roof.

Even with the other software I use, sometimes you can't use the auto roof tool, and need to sort of manually create the roof sections depending on roof.

So is the software some sort of secret?

Comparisons can be catalysts for betterment.

I am not posting out of professional courtesy.

I do not want to be accused of VW bashing.

It appears that one wall is not drawn exactly tangental to the turret.

Once this is resolved the Roof tool works to produce the following result:

Thank you bcd.

I did not think that VW could not handle this roof.

AS I have not had a 2008 version of the file I have not tried the roof tool.

Again,

thanks for looking into this.

Thanks everyone. I will go back into my file and make sure all walls are drawn correctly.

[cwailes]

BCD can you post the VW file that you created? I have recreated it several times and it either locks up or crashes.

[bcd]

This should work:

Thanks!

BCD,

Ok, I downloaded the file you uploaded and just for giggles tried to run the create roof tool on the edited poly you created and it does not work on my machine. I even set everything as you had on the roof object that is in the file and still no luck. Must be a bug. I am going to send the file in and see if they can reproduce the error in VW2011.
