For Home Design 3D contact support@homedesign3d.net or support@liveCAD.net

Home Design 3D files are directly integrated into the application, if you reinstall the application you lose the projects that you have not emailed before (knowing that they can not be imported after a reinstall) or save in DropBox.

At first, before opting for a reinstall, you should clear the memory of the device in this way, it is usually enough to restart the application.

In all cases, it is recommended to avoid letting the application open in memory after use, use the instructions above to completely close Home Design 3D.

(To prevent problems when opening the application, especially with big projects, one trick is to close your current project and then open one composed of few elements, such as a single room empty before closing the application. When you will launch Home Design 3D this project will be loaded at opening, which will minimize the risks).

You can save and share your projects between several iPad / iPhone using iCloud Apple system or Drop Box.

For this, you need to use the same iCloud account on both devices (Menu Settings > iCloud). In addition, you need also to enable the iCould function in Home Design 3D (Menu Settings > Home Design > Use iCloud).

On iOS you cannot save your project on your device. What we recommend is to export all your projects on Dropbox where they will be saved. You can use Dropbox, if you change your device (import feature) or want to share your project.

Buying the complete version of Home Design through the free version (In-App) unlocks the backup and save functions of the software only, the content remains the same.

There is no way to recover the lost projects, normally this problem can occur if you reinstall the application or if you have not saved, or duplicated, your projects (forced saving).

Using iCloud feature also enables you to share projects between multiple devices.

To force the application to perform a backup, which is normally automated, use the Duplicate command or New Project of menu “Projects”. These commands will create a new project and switch to it while performing a backup of your current project.

To print 2D plan you can send your plan by email and print the PDF file, or use the capture option of “Projects” menu (add to gallery), or the capture function of IPad (Home+on/off buttons press) to add a photo to IPad gallery.

In 3D view, you can use the menu to capture a photo or send it by email. And you can also use the capture function of IPad (Home+on/off buttons press) to add a photo to IPad gallery.

It's not possible for now, but on room walls you can add windows/doors.

To force the save of project (auto save by default) you can use the Duplicate or New project options of project Menu (when you add or duplicate a project the app save current project).

It's not possible for now, you can use several projects for the floors.

To create a room with more than 4 angles (marks), you can draw another room and append it to the first one. You will see that 2 new marks have been created. Edit them freely to fit your needs.
