Upgrade RayCAD for AutoCAD to Version 10
- Compatibility with AutoCAD
version 2015.
- A
friendlier registration. The provided password will
enable multiple installations (for instance, work,
portable and home computer).
- The new Adjust command
 provides an easy way to study ray intersections,
adjusting surface parameters like location, direction
and surface curvature while getting instantaneous
feedback in the form of ray trace, spot diagrams and
spot size expressed in RMS. It provides an excellent
way to fine-tune your optical design.
- Even Aspheric using 8
coefficients. The even aspheric surface uses the even
powers of the radial distance to describe the
asphericity.
- Odd Aspheric using 8
coefficients. The odd aspheric uses even and odd powers
of the radial distance to describe the asphericity.
- Toroidal surfaces have been
added.
- Decentering of surfaces is
added, enabling off axis surface generation.
- Scattering traces. Each
refractive surface will cast a new reflected ray. This
can be up to 5 branches deep.
- RMS (Root Mean Square).
Value is computed when performing a Grid trace.
- Curvature Optimization and
Placement Optimization now support both Focus mode and
Collimate mode.
- Mirror Rotation
 takes into account the half angle due to reflection, so
you can simply point to where the reflection needs to be
and the mirror will rotate half of that angle.
- Gratings
 find the appropriate order. If wavelength falls outside
the free spectrum, the appropriate order is found and
used. This enables you to trace wavelengths covering
many orders.
- Input ray
 changes are detected. The program will now detect any
changes to input rays. You are free to stretch or move
the ray bundle without using the Gather command again.
- The input ray Gather
command
 can be set to use the last selection of input rays, so,
when changing wavelength or change of color emulation,
it does not require selecting of input rays each time.
- Save and load wave
selection. This is useful if a long list of wavelengths
has been created.
- Use existent input rays.
You can change wavelengths and color association without
gathering input rays each time.
- Automatic erasing of the
last trace can be turned on, there by eliminating the
"Erase last trace Y/N" prompt.
- Spot ID's are kept and will
automatically erase between traces, just like rays.
- Random ray and random spot count
can be controlled.
- Number of intersects per ray per surface can be limited to
prevent endless TIR.
- Great speed improvement.
AutoCAD is drawing rays and spots while calculation is being
accomplished.
