Why we like it

Stands out in the superhive library for tying every dimension back to a cited SAE section rather than a rule of thumb, so when the standard is corrected, the tool is corrected too. A demo video is available.

What is H-Point: Package Builder?

H-Point: Package Builder is a Blender add-on for automotive packaging, built around SAE J1100, the global automotive measurement system. Car design starts with size and proportion: where people sit, what the wheels and tires are like, and how big the vehicle is. This add-on gets that foundation in place by having you look up a handful of dimensions from real vehicles in your target size class and enter them, after which it builds a complete, correctly proportioned package directly in Blender. Seating position, sightlines, wheel and tire placement, and headroom are all organized and related the way a real studio package would be.

From there the package is yours to push. Raise the roofline, stretch the wheelbase, shrink the cabin, or add a third row, and every change ripples through the model automatically, keeping proportions grounded in a human body while you chase a vehicle that has never existed.

Every dimension traces back to a cited SAE section rather than a rule of thumb, so when the standard changes or gets corrected, the tool gets corrected too. It requires Blender 4.2 or later and is released under the GPL-2.0-or-later license.

Who is H-Point: Package Builder best for?

H-Point: Package Builder is best for car designers and automotive visualization artists setting up correctly proportioned vehicle packages in Blender before moving on to surfacing.

How much does H-Point: Package Builder cost?

H-Point: Package Builder is completely free to download and use.

Key features

  • Occupant packaging with SAE J826 kinematic driver and passenger manikins at the 95th percentile, correct skeletal segment lengths, and a planted accelerator foot that stays true to the pedal plane as seat height changes; includes independent torso angle control, 3-across seating, and a symmetric toggle for off-center placement
  • Seat reference profiles with seatback and cushion lines offset from the H-Point per the J826 template, plus adjustable cushion angle, seatback height, cushion length, and corner radius
  • Vision and headroom via the full SAE J941 SEP2002 eyellipse, with correct axes, 12-degree tilt, and a package-geometry centroid held fixed as a reference even as the occupant reclines, plus J1052 head contour and effective headroom clearance
  • Steering setup for wheel diameter, tilt, column reach, and offset tied to the driver position, and knee blocker clearance using the SAE L62 packaging clearance indicator parallel to shin geometry
  • Tire and wheel assemblies with full ISO/SAE tire code support across the complete aspect-ratio grid, independent front and rear configuration, tandem axle spread control, and half-inch commercial rim sizes
  • Bounding box and reference geometry (vehicle envelope, ground plane, wheelbase line, and section planes) organized automatically into named collections in the outliner
  • Edits ripple through the model automatically, so raising the roofline, stretching the wheelbase, shrinking the cabin, or adding a third row updates the whole package

Frequently asked questions

Does H-Point: Package Builder work with Blender 4.2?

H-Point: Package Builder requires Blender 4.2 or later and is distributed in Blender's Extension format. It has no external Python dependencies, so once installed it runs inside a supported Blender version without extra packages to configure. The add-on builds its package geometry directly in Blender, organizing the vehicle envelope, ground plane, wheelbase line, and section planes into named collections in the outliner. If you are on an earlier Blender release, you will need to update before installing it.

Does H-Point: Package Builder need any external dependencies?

H-Point: Package Builder has no external Python dependencies, no license server, no activation step, and no phone-home behavior. Installation does not depend on internet access or third-party libraries beyond a supported Blender version. Everything the add-on needs to build occupant packaging, seat profiles, the eyellipse, steering, and tire and wheel assemblies is contained in the extension itself, which keeps setup straightforward for anyone already running Blender 4.2 or later on their machine.

What license does H-Point: Package Builder use?

H-Point: Package Builder is released under the GPL-2.0-or-later license, and the developer notes you own what you install. There is no license server or activation to work around, so the add-on stays functional locally without checking in with a remote service. For the current terms and specifics on distribution or modification rights under that license, check the developer's page before relying on it in a commercial project or redistributing any part of it.

Is H-Point: Package Builder free?

H-Point: Package Builder is listed as free in this catalog, so you can add it without a purchase here. Licensing and pricing can change over time, so for the current terms and the most up-to-date details it is worth checking the developer's page directly. The add-on itself uses the GPL-2.0-or-later license and installs through Blender's Extension format, with no activation or license server to manage on your end.
