Feature Requests

At the end of a construction, I usually add Chamfer to the entire model piece by piece. After an undetermined number or point in time, you can no longer change or add anything to the model. The app will close immediately. Reproduced on macOS and iPadOS, latest official versions (no beta).

In advance: Thank you so much for this great application! I'm thrilled! Thanks for your efforts!!! Here are a few feature requests and bugs. Features: as with chamfers, it should be possible to create radii on object edges Implement the creation of folders for projects on the home page Bugs: Please make menus floating, they are often in view and cannot be moved (particularly noticeable with the sketch menu, on iPad it is always centered in the middle of the screen) Diagonal construction lines interfere when creating a rectangle with a center point and must always be removed manually, these are m.E. not needed/useful when you edit a sketch, the solid you have already created does not change (Re-) naming the file names from the start page does not change the name within the project For new projects that you create when another one has been edited before, the project name of the previous one is always transferred instead of saying “unknown” there A solid in the 3D view cannot be rotated completely freely, you reach turning limits, which makes the whole thing cumbersome mathematical calculation functions, e.g. when entering lengths, would be helpful 3D rotation is a bit too soft, could be more direct and faster m.E. The zoom is unfortunately limited too early, which makes editing sketches and objects almost impossible even in the mm range, in particular this limits the selection of lines z.B with the Apple Pencil. If 2 parallel lines of a rectangle are 1 mm apart and you want to select the area in between, this is impossible because the lines are always selected, etc. Within a sketch, created lines, regardless of the type, that lie above a reference line, cannot be selected; the reference line is always selected Thank you and best regards Marc

In other professional CAD tools the sketcher environment displays sketched lines in different colors/hues depending on the status of constraints. For example: non constrained lines are shown black Constrained lines are shown in a dark green And a fully constrained sketch is shown in a bright/light green This is helpful for determining if the sketch is fully configured or if there are constraints missing which could cause problems later on in the process. Also this would make the lines more visually distinguishable from each other in the process of sketching and constraining.

CAD Macro / Workflow (parametric) General workflow Define parameters: nominal diameter d, pitch P, length L, tolerance class (e.g., 6H/6g), right‑hand or left‑hand thread. Create the core hole (for internal threads) or turn the shaft (for external threads) according to the core hole diameter or shaft diameter taken from the corresponding table. Tolerances & representation: use a cosmetic thread for drawings OR a modeled thread for simulation/rendering

I would like to propose a significant enhancement to the dimensioning system: the ability to use mathematical expressions directly within input fields and the implementation of Global Variables (Parameters). ​1. Inline Calculations ​Currently, dimensions require static numerical values. It would be highly efficient to allow basic arithmetic directly in the input field. Example: Instead of manually calculating the outer diameter of a ring, I could type 34mm + 4 to get 38mm. ​Benefit: This speeds up the workflow and reduces "mental math" errors, especially when working with offsets or wall thicknesses. ​2. Global Variables & Parameters ​The addition of a "Variables Manager" would be a game-changer for iterative design. ​How it works: Users define a variable (e.g., Tolerance = 0.2mm). This variable can then be used in any dimension field instead of a fixed number. ​Use Case (3D Printing): When designing parts that need to fit together, I could use the Tolerance variable for every gap. If the printed part is too tight, I simply update the variable value in one place, and the entire model adjusts automatically. ​Why this is important ​- Efficiency: Eliminates the need to manually hunt down and change dozens of dimensions when a single design requirement changes. ​Accuracy: Ensures consistency across the entire project (e.g., maintaining a uniform wall thickness). ​- Professional Workflow: Moves the app closer to industry-standard parametric modeling, making it much more viable for technical engineering and 3D printing enthusiasts.

Currently, if I want to select a specific sketch profile that is "hidden" inside a solid, I have to expand the "Solids" category and hide every single body individually. This is very time-consuming. Proposed Solution: Category Show/Hide: Add a visibility toggle directly to the parent folders (e.g., Sketches, Solids, Planes...). One-Click Isolation would allow users to hide all solids at once to focus on a sketch, and then bring them back with a single click.

Missing parts in the exported step file, created by Part3d itself. Please correct, thank you.

Creating objects in part3d and then exporting to stl and obj, the faceted ones become irregular and asymmetric, making it difficult to clean the polygons (focus on product design for advertising). Please refine the export, thank you.
