TOPIC:

The above was created by creating a standard gable roof to sit on the supporting walls., with the correct pitch and overhang.

Select the roof and in the Roof construction dialog, select the Wood dimensions entry and edit the various timber sizes to match your requirements. The Inferior purlin is the wall plate.

In the Premium version you can then edit the roof construction further.

You can delete the Collars, or lower them to become your rafters. If you delete the collars you will need to insert new rafters.

You can nove the Ridge purlin to be flush with the top of the roof ridge.

There is an example of a similar roof construction in the Training Course , where we use the roof editor and then modify the position of the wall plate and other timber sizes. Currently chapter 24.2

switching the grid off helped thanks project enclosed and a quick drawing of what roof structure im sort of trying to achieve in a section view
on the project

Hugh,

Happy new year to you too, and of course to all our users.

You have Visual Building Premium, which will allow you to edit any of the roof timbers. You can delete and add purlins and rafter as you need to. Email us your project with details of what you need moved and we can show you how.

When placing a wall if you hold down the Ctrl key, the wall will snap to 15 degree increments, but its best to have the grid switched off when you use this feature.

hi admin, happy new year to you all.
is it possible to alter roof structure so to have a ridge board running between top rafter joint as opposed to having a ridge purlin running under the top rafter joint. then also to tie the rafters togather at the bottom of roof sat on top of the wall plate and minus a concrete floor. one more thing is remove battern with plasterboard on internal edge of roof rafters. just trying to create a standard garage with timber rafters and tie beams/joists visable on inside or is this just a case of changing visable layers?
and while im here is there a way of making making walls go on 0,90,180,degrees more accuratly (i have snap turned on) it may be more to do with dimensions they seem to be a little off angle with the measurements im tring to put on section views or is this just my poor mouse control?
thanks
