Other programs for architects:

• Revit;
• AutoCAD Architecture;
• AutoCAD Civil 3D – more suitable for engineering communications;
• Chief Architect – better suited for home design;
• Rhino3D;
• CATIA;
• SketchUp – helps with architectural sketches and drawings;
• 3D Studio Max;
• Solidworks – more suitable for engineers.

After planning the model, the next step is to choose the scale that best suits a particular project. This decision is influenced by two factors: area and detail. If you need to show large areas, such as architectural models of cities, set the scale to 1:500 or 1:1000. This way, the model will not be too large and will be easily accessible for viewing.

For a single building, choose a scale of 1:200 or 1:100. At this scale, you get a fairly detailed detail, and windows, doors, and balconies will be clearly visible. To show only part of the house, a scale of 1:20 – 1:50 is suitable. The larger the scale, the more details you can distinguish.

How to make an architectural model: houses, neighborhoods, cities
Creating a model in any program follows the same principles. A building or complex of buildings is assembled from elements: windows, doors, walls, ceilings and floors, and so on. One model contains hundreds or even thousands of elements – the number depends on the object of modeling and the taste of architects. Different designers include different elements in their creations.

Stages of model creation:

• construction of sealed solid frames;
• removal of unnecessary holes;
• checking the topology and counting polygons;
• inverting the normals;
• finding overlapping surfaces;
• Removal of moving elements;
• smallest printable features (SPF);
• enhancement and support;
• architectural layout must be empty;
• removal of unnecessary geometry.

Create impermeable elements and remove dips

3D printers like to be given models that consist of geometrically correct objects – wireframes. Elements should not be permeable, for example, a hexagon has all six faces. If it has only five faces, then it is an open frame with a hole. Geometry with holes is often printed incorrectly.

When removing holes, use the rule: all adjacent triangles have two vertices in common. This way, a continuous surface without gaps is achieved. They are removed by special applications and manually.

Dips in the surface also occur due to file conversions from one format to another. Sometimes the number of missed or distorted polygons is so large that you have to align them manually.

There are two types of scanning: contact and non-contact. The first one is quite simple – during direct contact with an object, the equipment captures its parameters and creates a three-dimensional 3D model. The second method is a bit more complicated. It is divided into two types:

• active – special waves (X-rays, light, ultrasound) are directed at the object, and then the scanner records their reflection;
• passive – the device captures the reflection of natural radiation, and no special waves are directed.

All types of scanning demonstrate equally good results. As a rule, there is no particular difference in the quality of the object. When choosing a 3D scanner, pay attention to the conditions in which you plan to work (for example, whether it is possible to get direct access to the object or whether you will have to scan at a distance, whether natural light is available in the room).

3D scanning is often used in cases where it is necessary to create a high-quality copy of any part. This allows you not to make it anew, but simply reproduce it using a special device. Most scanners can be used for objects as small as one centimeter. The maximum size depends on the specific model.

How to make a 3D model based on a real object

This type of 3D modeling is less popular than the others. It is quite often used when it comes to working with real objects, using a 3D scanner. If for some reason this is not possible (for example, there is no such equipment at the moment), then 3D modeling is used.

The specialist performing the work moves the object in such a way as to create a 3D model as accurately as possible. This method is best suited for small objects that move easily. If possible, the object is even disassembled into separate components.

In the modern world, 3D modeling has become a new trend. It is widely used in various industries, art, architecture, and cinema. In addition, 3D models can be used to solve everyday tasks, and it has become much easier to create many items.

If there is a desire, everyone can understand how to make a 3D model. A special program for creating a 3D model from a photo or drawing is quite easy to use. At the same time, to achieve the desired result, you need relatively little: a prototype (in the form of a drawing, photograph or real object), special equipment and the necessary software.

This process is not as simple as it might seem at first glance. There are several stages in 3D modeling, which may differ depending on what the prototype of the future figure is. Drawings, photographs, and even real objects can be used to create it.

The method of modeling using drawings is considered the simplest. Drawings for 3D modeling are special design documentation that contains all the necessary information about the object. At the same time, the data is presented in sufficient detail, with all the necessary nuances indicated. The drawing must contain the following data about the object:

• design features;
• dimensions, parameters;
• materials.

At the same time, it is important to understand that one-sided drawings are not suitable for 3D modeling. The design documentation must contain clear information about at least three sides of the object (front, top, side). Otherwise, it will not be possible to recreate the object as realistically as possible.

If you are working on creating a 3D model from a drawing or plan to order its production in a specialized center, you should pay attention to all the details that the prototype has. You can familiarize yourself with the method of its manufacture, features of its use, and individual fragments. The more information you learn, the higher the guarantee that the 3D model will be identical to the original.

To create a 3D model from a photo, you don’t need to know the exact dimensions of the object. Creating a 3D photo is especially important when a person does not have the opportunity to visit the object (for example, it is too far away or its visit can be dangerous to life and health).

Just like for other types of modeling, photogrammetry uses special equipment. To get the highest quality 3D model from a photo, you need to prepare at least three pictures of the object (side, front, and top). In order to create a 3D model from a photo, all three images must be the same size. If we are talking about a person, animal, or any other living object, you can additionally prepare a half-profile image for 3D from a photo. As in the case of working with drawings, it is very important to take into account all the existing nuances. This will improve the quality of the finished 3D model from a photo.

Photogrammetry also has its drawbacks. For example, the internal structure of an object will have to be modeled additionally, because in most cases it cannot be conveyed using a photo. For this purpose, a special program is used to create a 3D model from a photo. You may also need to do additional technical work on other details if you are creating a 3D model from a photo.

In addition, it is important to understand that you need to be very careful when preparing photos. If they are of poor quality, the modeling result will be corresponding. In general, generating 3D models from photos allows you to achieve a good result.
