Schedule for Hips, Ridge, Valley, Gable, Eave...

[Steve Jepson]

I am not getting accurate schedules for roofs.

In this example I have two identical roofs systems. One a multi roof and the other has been split into individual roofs.

Notice that the calculations are not all the same.

I did this test because my roof schedules are not reliable or accurate.
They also do not match manual calculations for lengths of hips, valleys, etc...Surface areas I think are ok I haven't manually tested them.

Am I doing something wrong? This example is not nearly so bad as others I am working on.

It is a bit of a worry that the multi-plane roof is calculating 11 surfaces when there is clearly 12.
It is adding surfaces 9 & 11 together but I can't see from the image which ones these are.
It seems to be getting everything else right (well consistent at least) except for the hip lengths but I can't make out which if any is correct.
It seems to have nothing to do with them being added together - the total for those tow adds to the total of the multi-plane surface (the second one).
If I had to guess I would say the multi-plane roof has the hips correct as there are two surfaces that don't have hips.
The single roof planes all have a value for hips.

Thanks for taking a look at this. It is frustrating that so many times I can not trust the results of the interactive schedules.

I am trying to make a roof plan with schedules for a client in New Zealand and I am in trouble for this reason, but also because of the complications of working with metric units, strange unit sizes, and strange words. Nogging ? Clouts ? To complicate matters the materials are manufactured here in the US and are not very compatible with standard units the products are sold in or ordered in.

You can see the ID labels better in this picture.

Note roofs 11 and 12 for example:

The eaves, ridges, valleys are dimensioned. The superscript is the length on the slope. Nothings is correct except the eave length. This being the case, nothing in the schedule can be trusted.

I want this fixed.

Also I count ten hips on the roof - schedules have 9 on one 12 on the other.

Most of the figures are correct as you mentioned before - they show half the total length.
The worrying part here is the "hips" on 11 & 12 which are actually "gables" and as they are not touching other roof surfaces they should not be halved.

I can see now that roof planes 9 & 11 have exactly the same length eave (pitching line) which is why the multi-plane roof has added them together as one surface.
To me this is a bug but you could try unchecking the "show uniform entry as single entry" in the schedule.

The multi-plane roof is correct - remember it is adding two roof lanes together as one entry so in fact it is listing 10 not 9.

The single plane roofs are counting the gables as hips and adding the total lengths of gables and hips together for each surface which is why it is listing 12. It thinks every roof has a hip when in fact 2 of them only have a gable.

The number of ridges and valleys are not correct either.

It is not just the totals that are important. I need to have an accurate report of individual lengths as well, and they need to match the plans.

Also, if you make a schedule that shows all of the available fields for roofs some of them like Gable Length will show nothing at all.


This picture is of another situation where it does not show the length of the eave correctly - see roof 3 - the schedule did not pick up the 10m length.

In the image attached everything seems to be OK except the multi-plane roof has added two surfaces together and the single planes have included the gables as hips.
Check the status of the edge of the roof and see if indeed they are set as hips or gables.
