If you don't want the pitch to change, it needs to be locked. Click the Lock radio button beside pitch before making other changes. if you want to raise the entire plane up or down with no other changes, try Transform/Replicate.

Offhand I can't point you to anything specific, but it's covered in the documentation. There is a tutorial linked under the Help menu, and links to PDF format Reference and User guides as well. The hour long getting started webinars posted on the Chief Architect YouTube channel are also good resources. You want to try and set all the defaults you can before starting the plan as this will generally result in a better model with fewer problems. Wall defaults can be frustrating as you think everything is set and still the program is using the wrong wall type or materials. Once you think things are set, I like to create a simple test model to see how things are working.

Adding an image so others may not need to download and open the plan is always helpful I did not look at the plan, but you can easily change a roofs height with Transform/Replicate, or from within the roof plane dialog. What sort of "goofy results" are you getting -- pictures?

Your defaults for walls and wall materials are not set correctly so the software is filling in what it thinks should be there. An easy fix is to use the Material Eyedropper and paint the green siding to match the other.

You need to do it manually. Electric does not connect floor to floor.

Look at Roof Structure in the roof defaults.

Can you explain more about what you are trying to do? What 3D view camera type? What are you referring to when you say the wall top?

Open the door specification dialog and review your options. Open Help and search

If you don't need framing, you could make that wall from a slab, soffit etc.

Draw and align the 1st floor wall. Copy, then Paste/Hold Position on the 2nd floor. No special settings needed. Do you know about the Align With Floor Above/Below tools that show in the Edit Toolbar when a wall is out of alignment?

It looks like you should be asking in the SketchUp forum Not understanding the problem.

You can often draw CAD lines and dimension to them. Make parallel/perpendicular is your friend.

No. You need to use one of the Cross Section cameras.

Contact Chief Architect directly.

No

Isn't the answer obvious

Yes, you missed a step. -- right at the end. The article would say if there are automated ways of doing this. There is no way to set the default thickness of a truss. Like the article shows, you create a single truss, make your changes, then copy it to other locations. Trusses build between the roof and ceiling. Adjust those 2 things, build your truss, then change them to show the truss as you like. Read about the settings in the truss specification dialog like Force Rebuild

Have you reviewed the documentation on trusses available on the Home Designer web site, watched videos, searched the forum?

Quick howto on doing this with manual roof planes. Watch on YouTube: http://youtu.be/TaWh1MhYcUY?hd=1

There are several ways to do this. Draw a Room Divider across as I've shown here and set it to be a Full Gable wall.

Did you If that does not work, reinstall and use the Repair option.

A screen capture would be helpful. Try Preferences, Reset Options

You have both Patterns and Textures to change. Make sure you change both, then post back if you still have a problem.

Post the plan.
