Object properties
The left-hand panel of the editor holds everything about the object as a catalogue component, rather than about the shapes it is made of: its name, where it files, what it weighs, what it costs, and how its card is framed. It is worth filling in as you go - these are the figures your bill of materials will use every time you place the thing.
None of these fields are on the editor’s undo stack. Undo steps back through the pieces only, so it will not restore a name or a weight you have typed over. Retype it, or press Cancel and start again.

What it is. The text field at the top of the left panel, under Name. A new object arrives pre-filled with Custom object.
What it does. Names the component. It is the label on its catalogue card, and the name a copy you place takes in the Object List.
Options and limits. Save is greyed out while the field is empty, so every object gets a name. Any text is allowed and names need not be unique - two objects called “Shelf” are two different objects, told apart by their cards.
A placed copy takes a snapshot of the name, so the two can drift apart in either direction: renaming a copy in the Object List does not rename the object, and renaming the object here does not go back and rename copies you placed earlier. New copies get the new name.
What it affects. The catalogue card, and the name of copies placed from then on.
Category
Section titled “Category”What it is. The dropdown in the Bill of materials block, showing Select category until you choose one.
What it does. Files the object under one of the catalogue’s categories, so it turns up under that filter chip alongside similar components.
Options and limits. The list offers every category the built-in catalogue uses, plus Add new category…, which opens a small field for one of your own.
A custom object always appears under the catalogue’s Custom chip, whatever you choose here - choosing a category makes it appear under that chip as well. Leaving it blank is therefore perfectly workable; it just means the object is only ever found under Custom.
What it affects. Which catalogue filters show the object. Nothing about the design.
Weight
Section titled “Weight”What it is. The - value + row labelled Mass, in kilograms or pounds depending on your
unit setting.
What it does. Sets what one of these objects adds to your van’s Added weight total once placed.
Options and limits. It starts at zero, and it stays zero unless you set it - the app cannot guess what your shelf unit is made of. The steppers move 0.1 at a time and typing takes any figure; it cannot go below zero.
The figure belongs to the object, so changing it here changes it for every copy of it in the van. To correct a single placed copy instead, override it on that item’s bill-of-materials page, which splits that one onto its own line.
What it affects. Your added-weight total, once the object is placed.
What it is. The row below Mass, in your chosen currency.
What it does. Sets what one of these objects adds to your running cost total.
Options and limits. Zero by default, like the weight. The steppers move a whole unit at a time and it cannot go negative. Same rule as the weight about copies: this is the object’s price, and a single placed copy can be overridden on its own bill-of-materials page.
What it affects. Your running cost total, once the object is placed.
Thumbnail angle
Section titled “Thumbnail angle”What it is. The - value + row labelled Spin in the Thumbnail block, in degrees.
What it does. Turns the object about its vertical axis for the picture on its catalogue card, so a wardrobe is not photographed from the back.
Options and limits. The steppers move 15 degrees at a time and the value wraps, so stepping past 359 comes back to 0; typing takes any angle. It is display only - the object itself is not rotated, and a copy you place is unaffected.
Switch Result on to see the spin applied live, since the card is rendered from the fused object.
What it affects. The catalogue card only.
Frame the thumbnail
Section titled “Frame the thumbnail”What it is. The Show thumbnail camera button under the Spin row.
What it does. Swings the editor’s camera to the exact viewpoint the catalogue card is rendered from, framed the same way, so you can line the shot up.
Options and limits. It moves the camera and nothing else - you stay in the editing view, with your pieces still separate and still selectable, which is the difference between this and switching on Result. Press it again after changing the spin or resizing a piece to re-frame.
What it affects. The camera. Nothing in the object.
