If you try to place your structures and they sometimes revert back to their original position, you'll need to quickly change a setting in your browser:
For Safari & Chrome
- Look for your browser's File, Edit, View, etc pull down menu
- Select View
- Select Actual Size
- Refresh your browser
For Firefox
- Look for your browser's File, Edit, View, etc pull down menu
- Select View
- Select Zoom
- Select Reset
- Refresh your browser
If resetting your zoom does not work, you're probably running an extension that doesn't agree with the build tool.
Try disabling extensions in your browser to ensure there are no conflicts.
If it's still not working, try using a different browser. Sometimes Windows browsers do not jive well with our builder tool.
If all else fails,
and we'll see what we can do to help.
