How Do I Simplify an SVG Before Exporting a Laser File?
Open your SVG in Image to Laser, expand TRACE, and increase Simplify while comparing the drawing and POINTS count. Keep Smooth curves off for a controlled comparison. Check POINT BUDGET, download the ILDA file, then reopen it in ILDA Viewer to inspect the actual exported result.
Hi, I'm Trina with BeamTracer.com. This example uses an original Ripple Crest drawing with densely sampled curves. I want to remove redundant samples while keeping the outer ring, five-lobed center and small diamond recognizable. The Cinema preview below uses that exported artwork with the camera set to Orbit.
Software Cinema preview of the downloaded file. The camera orbits a single static ILDA frame; the SVG itself has not become an animation. This is a simulation, not a recording of a physical laser.
Before you start
Use a desktop browser with WebGPU support for Cinema. These captures use Studio access for the clean Cinema preview. ILDA download requires sign-in and an available export allowance; Studio includes unlimited ILDA exports. You can inspect a file in the free ILDA Viewer. See plans and export limits.
What does Simplify change?
An SVG can contain many closely spaced samples along a curve. Simplify removes redundant source samples. Watch the outline as you increase it: the goal is fewer points with the detail you need still visible.
In Image to Laser, import your SVG and open TRACE. For the comparison below, Smooth curves stays OFF, the device stays Standard 30k, and Target frame rate stays at 30. Only Simplify changes from 0.5 to 6.0.
Compare the same curves and the POINTS readout while the setting changes. The small diamond remains visible inside the five-lobed contour.
These are the measured counts for this drawing with no animation modifiers:
| Simplify | Points per frame | Estimated requirement at 30 FPS |
|---|---|---|
| 0.5 | 696 | 21 kpps |
| 2.0 | 371 | 11 kpps |
| 6.0 | 213 | 6.4 kpps |
The displayed requirements are rounded. Your source artwork will produce different counts. A smaller file or lower count alone does not tell you whether fine lettering or a tight curve survived; inspect the shape at the size you intend to use.
Should I turn on Smooth curves too?
Keep it OFF while judging simplification so you can see what one control changed. Smooth curves affects curved SVG paths; it does not round straight logo edges. It is a separate choice from reducing redundant samples.
If your source contains unwanted detail, remove that detail in the artwork itself. Simplification cannot decide which parts of your design matter. Remove unwanted lettering or decorative lines before importing an outline you are willing to keep.
How do I see where points are concentrated?
Expand VISUALIZATION and enable Show Point Density. Use the overlay to inspect where points gather, then turn it off to judge the normal artwork again.
The density overlay is enabled with Simplify at 0.5. It is a software view of the point distribution, not a measurement of light on a wall.
Why does the point budget change with frame rate?
The point-count estimate uses points per frame and the requested frame rate. More redraws per second require more points per second for the same frame. Target frame rate changes this estimate and preview timing; the ILDA file does not set your external player's scan speed.
Before fitting, the 696-point version needs about 42 kpps at 60 FPS, above the selected 30 kpps profile. Increasing Simplify to 6.0 reduces the source to 213 points, about 13 kpps at that rate. This comparison keeps the same drawing and device profile.
Read the source count beside KEEP ORIGINAL as well as the selected fitted count. Here FIT reduces the initial output to 500 points, while KEEP ORIGINAL still reads 696. The selected budget therefore reads 30 kpps and NEAR LIMIT before Simplify changes.
Leave POINTS on FIT when comparing the fitted output. KEEP ORIGINAL retains the unfitted point sequence; switching to it does not increase a device's capability. Recheck the drawing after fitting or changing the frame-rate target.
A point budget is an estimate
WITHIN describes the point-count estimate for the selected profile. It does not measure scanner stress, guarantee flicker-free projection or certify laser safety. Use Laser Safety before planning physical output.
How do I check the file I actually exported?
For the file shown here, restore Target frame rate to 30, set Simplify to 6.0, leave Smooth curves OFF, and use FIT 30 FPS. Press DOWNLOAD ILDA, then load that downloaded file in ILDA Viewer.
The Ripple Crest download contains 1 frame in Format 5 (2D True Color), with 213 total points and an EOF marker. Of those points, 173 are lit and 40 are blanked travel. The file keeps all three source colors. FILE HEALTH reports VALID and WITHIN for the selected Standard 30k profile.
Use 3D, open SCENE, choose Cinema, and set the camera preset to Orbit to inspect the same artwork in the view at the top of this article. Camera motion helps you inspect the software preview; it does not add animation frames to the file or establish that a physical installation is safe.
Load the actual downloaded file, check FILE HEALTH, then switch to the Cinema orbital preview. The file remains a single static frame throughout.
For the full conversion workflow, see SVG to ILDA. If you want the artwork itself to move or reveal over time, continue with animating a static SVG.
