Can images be vectorized in QCAD?

[JayPark]

Hello,
I’m wondering if it’s possible to vectorize images in QCAD.

I’m a leathercraft artisan, and I’d like to transfer a physical paper pattern directly into CAD.

If there’s another way besides vectorizing, please share it with me.

Thank you.

Hi,

Yes, please refer to the Trace Bitmap… reference.

Hello,
After some trial and error, I roughly traced the lines, but the shape made up of multiple points is much larger than the actual object.
What’s the best way to match it to the real-life size?

Hi,

A bitmap doesn't store it's geometric size except NxM pixels.
By default QCAD imports a bitmap as entity in the scale 1 pixel = 1 drawing unit.

The drawing unit of a new file depends on the user preference.

In my case 100 pixels wide would result in a design somewhat less than 100 times 1 pixel = 1mm or 100mm.
When the drawing unit is the inch then 100 pixels wide equals 100 inches by default.

3 options:
- Scale the bitmap while importing if a scale is known.
- After importing as default, scale the Bitmap entity to fit at least two known opposite real world points.
- Or scale the Tracing entities to fit at least two known opposite real world points.

Aligning references points with scaling is perfect for this job.
