@dunglh said: I have a dwg file. i have a dwg file. I want to use sketchup sdk (c++/c#) to import and convert it to glb (gltf). Is there a way to convert? Thanks! SketchUp SDK is for reading / writing skp files. For reading a dwg file you would need e.g.: AutoDesks's RealDwg SDK ( https://www.autodesk.com/developer-network/platform-technologies/realdwg ) and for writing gltf, you need something like Microsoft's gltf SDK ( https://github.com/microsoft/glTF-SDK )

Sketchup assigns persistent IDs by giving each object a unique identifier that does not change when the object is modified.

In the tree view on the left, select the base dimension style and click Edit. Click the Text tab. In the Text Color list, select a color for the text.

SketchUp uses the Windows/Fonts ttf font so install them there and restart SketchUp to see them listed ??

You have a reference to the entities of parent1. From which you can get the reference to the group. From that you can get it definition - group.definition You have a reference to parent2, and thus its entities Simply add the group's definition into that, retaining its transformation... Assuming parent2 is a definition... parent2.entities.add(group.definition, group.transformation) However, if parent2 is an instance use parent2.definition.entities.add(group.definition, group.transformation)
