My company has recently started using SoftPlan 2022 and I am having some issues with designing this roofline in the program. We have a 2D drawing (done before we started SoftPlan) but want to build it in 3D for our client. In the attached images, you can see how the missing valley (which has a much different pitch than the majority of the roof) effects what our final product is looking like. Is there a way to add a valley to a roof in SoftPlan? Or, alternatively, is there a better way to draw it in multiple steps to get the same result?

 

If anyone could give me any advice on what I am doing wrong it would be greatly appreciated!

The first thing that I see is that it appears you don't have the varying wall plate heights you need on the front of the house to get that roof . Go into roof mode and then check your "mode visibilites" (F9). There is the option there to turn on "plate height". Get everything right there and you you should see the difference.

Generally, I have found that really complex roof requires me to break the roof into smaller and smaller parts.. (no "auto-roof" for this one)...

 

also, if there is no need for an accurate materials take-off, then I am free to make all sorts of shortcuts (roof planes that cut through another roof, or through an upper floor)..  So one roof might run right through the attic of another roof, or the second floor bedroom... That works fine for an exterior rendering, or generating an elevation.. but not so much for materials take-off..

 

looking at the roof you have here, you are going to need to account for the fact that you have two separate ridge lines (roof widths).. you are going to need to add a perpendicular roof plane to reduce the width of the one roof (higher ridge), down to the width of the other roof (lower ridge)

My two cents. I like the roofline on the elevation on the right better anyway!

Thanks for the advice! What would you do in the instance you needed an accurate take-off? If I use the "cut hole" option will it detract from the materials or is that solely for visualization purposes?

Sorry I'm not going to be able to advise on materials take offs... I've been using softplan since it ran on DOS, all the while happily living in my bubble of not doing materials take offs..

Due to complication, this roof design uses 3 roofs.

Were you able to properly frame that roof for a structural sheet and softlist pricing?

I don't use rafters/ceiling joists, send the plans to truss supplier to do the layout.

We frame every plan we do , some do not lend themselves to being trussed. 50 years hands

on building with only a handful of the houses being trussable. Framing the house in Softplan

gives us an opportunity to catch any potential problem areas before the plans go out the door.

And it is a lot of fun!

That roof looks amazing! I would love to be able to learn how you were able to accomplish that in SoftPlan!

Russell , The roof was framed with a couple rafter calculations and material settings in Softplan.

 Framing it in Softplan all starts with a small roof and a few hours practice. Important to set tops of

walls , beam heights. rafter seat cuts/heel heights, ridge locations etc accurately for all to come

together.

I would add a framing member along the wall on that shed roof that attaches to the gable wall… ;-) and raise those two windows so you have room for flashing and window trim above that shed roof.

David Zawadzki ,

 

  The shed rafters will be extended into and fastened alongside corresponding vertical members given in the real world the rafters will be exposed rough sawn framing members and a horizontal ledger at the wall with exposed fasteners is not desirable.

There is 8" from bottom of the windows to the top of the shed roof, more than enough for adequate and proper flashing. As you and I know , especially after being in this business since 1969, every builder will do it different. I have been fortunate that after all the years swinging a hammer, just dated myself, and designing homes I have not had the pleasure of answering any lawsuits or had a need to file any claims using my contractor or errors and omissions insurance. Appreciate your input, I will try and do better in the future!! ;) :)

Steve,

 

Remind me to tell you the story of the 25 year old plan checker sometime...  :)
