Working with 2D projections

Choose visually a relative location of cameras using the graphics window with CAD interface. Use a lot of 2D/3D constructions and CAD tools, snaps, line types, font types, horizontal and vertical projections, up to 10 layouts in each project, unlimited number of layers.

2D modeling in horizontal and vertical projections is possible.

3D modeling layout and camera view areas

VideoCAD has special 3D World window with standard tools for 3D navigation (Orbit, Move, ZOOM, Walk, Look around, Zoom frame). With the help of the window you can observe the layout in 3D representation. You can work on the project in usual 2D projections and watch it in 3D. You can "walk" on the floors of 3D models of buildings and study every detail.

Possibility of loading prepared 3D models (a person, a car, etc.). Built in 3D model library.

You can import ready 3D models of objects and territories from files: *.3ds, *.ase (3D Studio max), *.dae, *.xml (Collada), *.obj and more than twenty 3D formats. You can download 3D models in Collada format (*.dae) from free SketchUP 3D Warehouse library, use 3DS Max models from designer's libraries, 3D models from game model libraries, create 3D models in SketchUP, save them in *.dae and import in VideoCAD.

You can create 3D models in VideoCAD itself from selected constructions and existing 3D models in any combinations, you can merge 3D models and constructions.

You can transform, rotate and tilt 3D models (including 3D models created from constructions).

You can cut out parts from 3D models, import parts from complex 3D models.

You can delete parts from 3D models.

You can import 3D models and scenes from SketchUp using free VideoCAD Plugin for SketchUP 2.0. The package includes a plug-in, an example and a User Guide with step-by-step instructions on how to add a new 3D model to VideoCAD library.

Possibility of using 3D models-territories, to place inside them cameras, constructions and other 3D models.

All constructions can be not only painted, but also covered by materials. Any raster images in the formats *.bmp, *.jpg, *.gif, *.tif, *.png can be used as materials.Using materials you can significantly improve appearance of images of the project.

Calculation and draw on layout the IR illumination zone (where the built-in IR illumination provides an image of the target with a quality not worse than the specified one) The calculation is carried out based on the camera parameters (sensitivity, lens aperture), IR illumination (wavelength, power, radiation angle, concentration) and the required target's image quality (signal-to-noise ratio).

Instead of a rigorous calculation, you can draw a projection of the IR illumination zone, setting only the maximum distance of the IR illumination and the angle of radiation.
