Logo ICad 3D+

ICad 3D + is the first software for the design and pattern of footwear that integrates in the same program two work environments, one virtual in 3D and one technical in 2D, which work in parallel and simultaneously. In this way, ICad 3D+ is presented as the best virtual alternative to the traditional design and pattern making process, considerably reducing both the time used and the material and human resources of the company.

Complete process

Design, create and modify footwear models, and their patterns, parallel and simultaneously in 3D or 2D with absolute reliability and precision. Make flattenings of any last, including boots and ankle boots, with total accuracy. Modify with a simple "click" The flattened, avoiding the repetition of the processes that would have to be carried out if these modifications were made manually. Create, or import, flats, heels, ornaments and accessories quickly and easily, thanks to its intuitive interface. Customize and get images that look as hyper-realistic as a photograph taken from real shoe models. Simulate shoe loosening by adding realism to your models.

Infinite possibilities

ICad 3D+, has been developed by the "Technological Institute of Footwear and Related Products (INESCOP)" Its more than 30 years of experience in the development of CAD-CAM products, together with its close relationship with companies in the sector, has allowed develop computer programs adapted to your needs, and always oriented towards continuous improvement.

Working with ICad 3D+ is very simple and intuitive. The first steps to start working are to import a digital last, prepare this last for the design of the model and start drawing on the last. You can then choose to work on any of the two ICad 3D+ work environments, either in the virtual 3D environment (creating outsoles and heels, adding volumes and thicknesses, creating accessories, etc.), or in the technical 2D environment (creating flats, patterns, grading, etc.) ), being able to change from one environment to another at any time.

Import of digital last

The first step of the process is to import a digital last.

ICad 3D+ allows a wide range of formats (HOR, LST, FVR, STL, IGS, SEC, OBJ, etc.).

You can modify the digitized last to create boot last, and even add or merge a mounting sole, internal wedges or platforms.

Preparation of the last

3D lasts

Create virtual lasts for boots and ankle boots following a simple procedure.

Flatten any last

ICad 3D+ achieves flattening of any last, including boots and booties, in a totally accurate and reliable way.
Representation of the 3D surface of the body and the plant on a 2D surface, in this way, any modification in the design line is automatically reflected on the other.

Technical flattening

Absolute accuracy

Obtain 2D flattenings of any type of last with absolute reliability and precision, and use them as a basis to create your patterns.

Save time and resources. With ICad 3D+, each modification made in the 2D design lines is automatically and faithfully reflected in the 3D design and vice versa.

Drawing on the last

Intuitive line design

Drawing on the digital last is as simple as drawing on a real last. Working with ICad 3D+ will allow you to: Use as a reference other model sketches, automatically smoothed curved lines, creation of lines of variable and constant width, insertion of shapes and figures, etc.

Flats and heels design

Materialize your ideas

Quickly and easily create any type of floor and heels with absolute precision. Using a wizard, you can create and edit the lines of the structure created to modify the component. Components can be exported directly to a 3D printer to produce prototypes quickly, reducing costs and time.

Creation of pieces and thicknesses

Instantly define 3D pieces

Quickly create all the parts of the model, either by selecting the sequence of lines, or with the function of a single "click". In addition, you can give your model realism by defining the thickness of the pieces, simulating overlapping, choosing types of profile, padding, stitching, etc.

Materials and variants

Photorealistic materials

ICad 3D+ is designed to speed up the creation of any type of material (leather, rubber, patent leather, metal, gems, glass, etc.) in any color.

Materials can be created directly in the program, through its materials generation wizard, or through the import of scanned textures that are easily editable with ICad 3D+. The created materials can be saved in your own virtual library for later use.

Settings that provide greater realism

ICad 3D+ allows to give the models an added realism, being able to simulate the real loosening of the footwear in which tension changes occur on some materials and parts of the footwear.

Thus, it is possible to perform a multitude of volumetric adjustments such as modifying tongues, altering instep lines, deforming heels and toes (lifting them up), widening shafts or even simulating wrinkles.

Imagine and make it come true

ICad 3D+ integrates an advanced high-quality rendering system that allows images (and videos) to be obtained so real that it is difficult to distinguish whether they have been taken from physical footwear models. Additionally, 3D models can be rendered on any simulated scenery.

Different camera perspectives, position lights at different points, or adjust the lighting to simulate particular lighting conditions until the desired visual effect is achieved.

Exports models and their combinations to ICad Colorways.

2D / 3D Pattern

Agility and precision

Make patterns quickly in a single click or by selecting lines.

It works indistinctly in 2D or 3D with the certainty that any technical adjustment will be represented millimetrically in the other working environment.

Add margins (mounted, folded, entrances, etc.) and decorations (figurative, chopped, seams, etc.), quickly and easily.

Using the "Texts" tool, organize the patterns to be cut on cardboard or leather, and facilitate subsequent production tasks.

Size scaling

Fast and easy scaling

Work using standard scaling systems or customize them to your needs. In addition, with the modifiers you can control the scaling of each of the baselines, and thus be able to block or scale lines individually to scale pieces such as straps, ornaments, labels, heels, zippers or boots.

Consumption, technical sheets and cut

Optimize leather consumption

Calculate the material consumption of the model in real time, and minimize waste. Thanks to the 2D / 3D connection, with ICad 3D+ you will be able to modify any line, and update the consumption instantly, without the need to re-flatten. In this way, you can modify the pieces to achieve the best possible use of material.


Customizable technical sheets

Create, and adapt to your needs, technical sheets for the design and production phases. Export them to pdf integrating any type of information, photographs and even rotatable 3D objects.


Cut your pieces on any cutting machine

Export your patterns to any cutting machine without any additional adaptation and without ever losing the correlation between 3D and 2D. Direct connection to ICad Nest
