Как конвертировать 3DM в STEP
- Добавьте ваш файл .3DM - перетащите его в поле выше или нажмите, чтобы выбрать.
- Конвертируйте его в .STEP за несколько секунд.
- Скачайте ваш новый файл .STEP.
Чего ожидать
- NURBS solids transfer exactly; any mesh objects inside the
.3dmexport as tessellated faces, which some CAD tools may import as surface bodies rather than solid bodies. - Layers, display colors, render materials, and text annotations are not carried into STEP - only solid geometry and topology transfer.
STPand.stepare the same format; rename the extension if a downstream application requires one spelling or the other.
Часто задаваемые вопросы
Does STEP preserve Rhino surface quality?
Yes. STEP stores NURBS geometry natively, keeping the exact mathematical definition of every surface - unlike STL or OBJ, which approximate surfaces as triangles.
Can I convert 3DM to STEP without buying Rhino?
Yes - use the free converter above, or Autodesk Fusion 360's free personal tier, which imports
.3dm and exports .stp.Why does the STEP file import as surfaces instead of solids in SolidWorks?
The source
.3dm had open surfaces rather than fully closed shells. In Rhino, run ShowEdges with 'Naked Edges' to find the gaps, close them, then re-export.Should I use STEP or IGES when exporting from Rhino?
STEP (AP214) is the safer default - it carries richer data and is accepted by all current CAD importers; use IGES only if a specific tool requires it.
