Tips of Pepakura Designer

Tips for Quick Edits

Quick edge selection

Double clicking an edge selects edges connected to the edge along the direction. This tip is for time-saving at the stage of selecting cut-lines before unfolding.

Quick angle adjustment

Double clicking an edge rotates the part so that the edge becomes vertical or horizontal when 2D edit mode is [Rotate].

Quick flap edit

Edges are selected by a rectangle area when 2D edit mode is [Edit Flaps]. Properties specified on the dialog are set to the selected edges.

Other Tips

Add the outline paddings

[2D Menu]-[Add Outline Padding] adds colored offset to the outline of pieces. At the stage of assembling, it makes gaps of glued area unnoticeable. This helps us to make good-looking paper models. The amount of the offsetting is changed through [Settings]-[Other Settings]-[Others].

Measure the distance between two points

[2D Menu]-[Edit Mode]-[Measure Distance between Two Points] command changes the edit mode to measure the distance between two points. This is used both on the 3D model and the 2D pattern. After two points are clicked, their coordinates and the distance are shown on a dialog. The value is the distance when the 3D model is assembled with current scale. The scale can be changed through [2D Menu]-[Change Scale]. The assembled size of whole model is shown at the right bottom of the window.

Change the rotation center of 3D view

Clicking a point on the 3D model after the command [3D Menu]-[Change Rotation Point] ([Ctrl]+W) changes the rotation center of 3D view. The clicked point becomes the center of rotation. [3D Menu]-[Reset Model View] resets the view position.

Advanced Tips

Update 3D model

[File]-[Update 3D Model] command reloads the modified 3D model, and then updates the 2D pattern automatically by checking the difference between the original one and the reloaded one. Pepakura Designer can also keep monitoring the updates of the file. Now you do not need to edit the 2D pattern again from scratch even after you notice the need of the modification of the 3D model.

Make smooth surfaces

[Subdivide Edges and Make Them Smooth] command on [3D Menu]-[Edit Mode] makes smooth surfaces by subdividing the selected edges.

Use Pepakura Designer as an UV editor

After editing the pattern, [File]-[Export]-[3D Model/UV Info (*.OBJ)] command exports the 3D model and the UV info to an .obj file. The UV coordinates are set as shown on the 2D pattern. This means Pepakura Designer can be used as an UV editor. The left bottom image shows the screen of Metasequoia, a 3DCG software, loads the UV set by Pepakura Designer.

Make a symmetrical model

First, make a half model on your 3DCG software. Second, make the unfolded pattern on Pepakura Designer and save it. Third, select [Others]-[Mirror Inversion] command, then both the 3D model and the pattern are inverted in x-coordinate. Finally, import the saved data (which is saved before [Mirror Inversion] command) through [File]-[Insert File (*.pdo)].
