Start with filled outlines at the intended size
Keep an editable copy of your original vector artwork. For a supported signage import, prepare filled contours that describe the areas you want to build. Pexure’s signage parser skips line and stroke-only elements rather than converting their visible stroke into a solid shape. If a stroked design is missing after import, convert the intended strokes to filled outlines in your vector editor and inspect that copy before importing again.
Check the outside boundary and each interior opening. Text counters, such as the center of an A or O, need to remain open where the design requires them. Do not assume that every overlapping path has been welded into one contour. Simplify ambiguous overlaps in the source and compare the imported preview with the original artwork.
Confirm the artwork width in millimeters or your intended physical units. Page margins and the artwork’s own bounds are different measurements. Use a known feature to check scale, and consult the SVG print-size guide if another application interprets the file differently.
Wall height and wall thickness control different dimensions
Wall height controls the vertical extent of the sign structure. Inward wall thickness occupies space inside the artwork’s boundary. Increasing height does not create more room across a narrow letter stroke; a thick inward wall can consume that stroke’s interior even when the model is tall.
When the builder reports that wall thickness consumes the artwork, first confirm the imported size. If the scale is correct, reduce the inward thickness to suit the narrowest part of the design, or revise that part of the artwork. Enlarging a preview window changes neither the physical dimensions nor the available interior space.
Review small features throughout the design, not just the largest letter. A setting that works on a wide stem may fail in a thin decorative element. Keep a record of the intended size and settings so that a later revision can be checked against the same measurements.
Review acrylic and its supporting structure
Supported channel-letter workflows treat acrylic separately from the main wall-and-stopper object. The supports must fit inside the wall and leave the room required for the acrylic panel. Changing a stopper’s height or depth can make a previously fitting design invalid.
Choose acrylic thickness and fit settings for the material you actually plan to use. There is no universal clearance that guarantees a fit across cutters, printers and materials. Inspect the panel boundary and support positions in the preview, then make a small physical test before producing a complete sign.
Inspect the export as a separate deliverable
- Record the intended width, height and units before exporting.
- Export the supported model format and the separate acrylic output where applicable.
- Open the model in your slicer or fabrication application without automatically fitting or rescaling it.
- Compare the model dimensions with the values recorded in the builder.
- Inspect openings, wall connections and separate parts, then make a test piece using your production material.
A 3MF model can declare the units used for its geometry. Regardless of format, inspect how the receiving program interprets the file and check a known dimension. File creation alone does not prove that a mesh has been independently validated by your slicer.
Pexure’s 3D Signage Builder is a focused beta workflow for supported SVG designs. Keep the original vector source and the exported files. If the exported geometry or fit differs from the preview, resolve that difference before a production run rather than compensating with an undocumented scale change.
