With Pro and Enterprise you plan the PV module layout directly on the measured roof or facade surface, in every session with a 3D model. Roofy fills a surface with the module of your choice, leaves out obstacles you have drawn, such as chimneys and roof windows, and keeps the distances to the edge. You place, move and rotate single modules by hand, or several at once with a selection frame. Variants can be created side by side and compared in the report. The module layout is switched on by default and can be switched off in the organisation settings under Add-ons.

Modules can be planned with tilt mounting: as sawtooth or in pairs as gable or butterfly (east-west). Tilt and tilt direction apply to the whole surface or to single modules, and the buttons name the compass direction. A safety zone marks a strip along selected roof edges; it stays free or is listed in the report.

The PDF report shows the number of modules, the output in kWp and the layout for each variant. Where a roof surface can be matched unambiguously, a yield estimate based on sonnendach.ch is added. The DXF export can include the layout on its own layers.

A compass in the bottom left of the 3D model shows where north is and turns with the view. One click turns the view to the north.

Edge lines and dimensions in the 3D model sometimes lay inside the ground after a session was reloaded. They now sit on the roof surface again.

If a wall plan appears mirrored, flip it to the correct side with one click in the wall plan toolbar. The setting is saved with the measurement and applies equally to the PDF report and the DXF export. Edge lengths and areas stay unchanged.

Some planning programmes expect the height on the Y axis and otherwise show the model lying on its side. The new variant delivers the same data in an upright orientation. For AutoCAD, Rhino and PV*SOL the standard OBJ remains the right choice. The export dialogue now lists the four variants, each with its own note.

The GLB model now follows the glTF standard with the height on Y and is centred on the origin. Programmes that previously showed an empty scene now load it correctly. In the OBJ bundle, the model file once again references the material file that ships with it.

While polygons and measurement lines are hidden, right-click, context menu and edge grip no longer respond to the invisible geometry. Previously a right-click could delete a measurement line that was not visible at all. Visible objects behave exactly as before.

Rectangular areas now take three clicks: set the first side, then pull out the width. The rectangle may be rotated freely. It works when drawing roof areas, when measuring and on facades in 3D. A right-click undoes the last click.

Once a measurement line is finished you can carry straight on, as its endpoint becomes the start of the next line. That lets you measure a whole edge in sections without starting over each time. Escape ends the chain.

You can grab a complete side of a polygon and move it in parallel instead of dragging both corners separately. Available in the 2D plan and on facades in 3D.

Move a corner or a measurement line and everything attached to it follows: shared endpoints, points sitting in the middle of a line, and across several connected lines. The junction between roof and facade at the eaves holds too.

When drawing on a wall, lines now snap reliably to right angles and to the horizontal of that particular wall surface. The guides show the direction the next point will land in.

The shortcut overview in the app and the guide now show the same, complete list. Newly covered are the rectangle tool, moving whole sides and navigating the 3D model, among others.

When uploading, you now choose between 2D (a fast survey from the orthophoto), 3D Classic and 3D Alternative. Both 3D modes additionally generate an interactive 3D model and differ in the calculation method. If 3D Classic does not convince you, simply reprocess the session with 3D Alternative.

The automatic ground trim now detects the ground edge from the point density and removes hanging ground remnants beneath the building more reliably, without cutting into the building itself.

Individual images with faulty GPS coordinates are detected and corrected instead of distorting the entire model.

On particularly large orthophotos (over 8192 pixels edge length) measurements could be slightly offset. The scale is now computed uniformly across the full resolution.

The height from the ground line to the roof edge is now measured along the wall, no longer along the sloped roof line.

The sign-in token is cached during upload and refreshed automatically when needed. Uploads no longer abort with a token error.

In rare cases an image upload could stop partway through with a subscription notice. The subscription check now happens when you create a project and when you start processing, no longer for every single image.

Ground and surrounding remnants beneath the building are removed automatically, even on slopes. The model sits cleanly on its footprint without manual trimming.

The 3D model now loads in seconds instead of minutes thanks to optimised textures. The 2D view opens around ten times faster.

While cropping, a rubber band previews the next edge and the outline snaps to the starting point to close. The orthophoto and height map are cropped along with the model and reload automatically.

On roofs with both flat and pitched areas, every roof surface is now assessed individually. Swapped edge types and the resulting length errors are fixed.

After cropping, the height map shows exactly the same extent as the orthophoto, even after reloading the page.

The image no longer rotates while a polygon point is being dragged. Automatic alignment only kicks in after you release the point.

Cropped 3D models keep their photo textures. The grey, untextured model after cropping is a thing of the past.

If the page is reloaded while processing is running, the status display now shows the actual progress again instead of being stuck on “Starting”.
