Some lines failed to render

[MaticDiba]

Hi, I am using QGis 3.2.3 and Qgis2threejs 2.2. I was trying to export 3D model of realtively dense lines. I imported them as dxf files. Some lines failed to render. There are empty spaces between lines. Simple projec demonstrating that is available on wetransfer: https://we.tl/t-Jo881Jp4Nd (dxf is also present)

When I imported simpler (less dense) model, all lines were rendered. I tried to open dxf in another viewer and it seems the file is Ok.
