Get accurate terrain models instantly. We support most CAD platforms, and offer a wide range of customization options to ensure that the product is precisely as you want it.
Lasercutting small areas used to result in an unwanted "polygon" look due to the 2x2m resolution of the underlying data.
You can now specify a Smooth parameter for your laser cuts. This will tell Cetopo to smooth out the resulting contours for better aesthetics. The parameter is in millimeters, and specifies the maximum deflection of the curve. Lower values are thus smoother. If you prefer not to smooth the data, you can leave Smooth as 0.
Smoothing is an aesthetic preference. Sometimes a polygon look is preferable, or maybe you want something even softer looking than what smooth produces. Reduce allows you to reduce the amount of data points that are used. Reduce is also in millimeters, but specifies the minimum deflection of the curve. Higher values are more reduced. Leave Reduce as 0 for no reduction.
Reduce is applied before smooth. For example, Reduce = 5, Smooth = 0.01, will first reduce the curves to 5mm deflection, and then smooth them to 0.01mm deflection, resulting in a very smooth, but inaccurate result. Aggressively reducing the data might result in bad laser cuts, with layers that dont stack properly. Experiment with different values and use the 3D-preview to verify how it will look!
Automatization is nice as long as it does what you want. Some user-feedback has now been implemented!
The nester now allows you to specify a minimum separation between parts. This can be useful in improving cut accuracy and finnish quality, as well as making the file more readable.
Cetopo now allows you to run the algorithm for much longer to improve nesting. There is a Quick Nest option in the Laser Cut settings which allows you to toggle the nesting duration between ~5sec and ~30sec.
It can be hard to judge how large something is when its floating in space on a computer screen. You can now add a reference coffee cup to the preview window. The coffee cup is 80mm tall and 80mm in diameter.
The laser cut preview is rendered with a real "laser-cut-plywood" photo-texture. The texture is correctly scaled to your model size. You can almost feel the wood!
Laser cutters are awesome tools that enable us to do wonderfull models. Provided that we have the ability and time to draw those models in the first place.
The new laser cut feature in Cetopo aims to solve all laser cutting related problems for the user.
