  • This app hasn’t received enough ratings or reviews to display an overview.

Scale, measuring, and German shot sizes • The grid has a scale. You decide how many metres one grid square stands for, and a scale bar appears at the bottom left if you want it. It is aligned to the grid — so you can count squares — and it now also travels into the PDF and the exported image, where it is most useful. • New ruler in the toolbar: tap two points, read the distance. It snaps to object centres and wall corners so the number is actually right. • Metres or feet and inches, set per project. • An imported floor plan can now be moved: switch on "Align background" in the stage panel, drag the image into place, switch the mode off again. • German shot sizes are now actually German in the German app. Two additional sizes were added to complete the ladder. • In the shot list the focal length now sits next to the shot size, and the estimated shooting time has a row of its own. • Fixed: with camera setups, the shooting times of the individual cameras were added up. Cameras in a setup shoot simultaneously, so the time belongs to the setup and is no longer counted more than once. • Fixed: exporting an image could produce black borders if you had zoomed out beforehand. • The "Movement" column is gone from the Excel, CSV and HTML exports. It only held technical abbreviations, and what the camera does is told by the camera symbols and movement paths in the plan. • The help has a new chapter "Scale & measuring" and now also covers the context menu, the zoom slider and the aspect ratio.
