lines and surfaces

[Chas / Aug Posekany]

I must be in a brain fog today.

Someone confirm that Nxt does not like lines with width as AR3 did but will render lines extruded into surfaces?

What's a line with width?  A polyline with width?-- a line with thickness?  Either of those should work OK-- although I always recommend more contemporary 3d objects like surfaces and solids.

I seem to remember someone having issues with polylines with a thickness set in the properties box.

I have drawn a series of polylines and extruded them into surfaces and it seems that Nxt is ignoring them.

It depends on what the polyline is doing and the effect you want.

Way back in October of 2009 I ran this test (see attached photo), it should give you a good idea of what AR5 understands about "lines with thickness" or width. Unlike AR3 and AR4 it does not like curves and renders them as straight segments.

This may have changed in the last year.

 

Note: Straight segments of polylines will render correctly - I use them for parking lot stripes and expansion joints all the time. The example image uses all the same smooth pline made up of straight and curved segments. They just render differently depending on how they are changed to represent a surface or solid.

What I've done is; instead of using a closed polyline and extruding a solid. I used a open polyline and extruded a surface.

Nxt don't like it.

What do especially for kerbs and car lot markers is to draw a line, arc etc as it is applicable to my present need. Convert them to polylines and give them width. With properties dialog box I give them thickness, then convert them to solids. This nxt likes and renders well.

Even to surfaces receiving decals I do the same only with width of about two.

This is what I ended up with, the tinsle didn't render. All the tinsle is done with straight polyline segments extruded into surfaces.

The rendering didn't run very many passes but obviously ignored the surfaces. I'll try something else.

[akinlolu olugboji]

Assign width and thickness to your polylines either straight or curve, then covert them to solids.

 

[Chas / Aug Posekany]

I had added width and then extruded as surfaces. Once I had trouble with that I exploded the surfaces to regions and Nxt still ignored them. I think I messed them up when I extruded them for some reason. I appreciate your help trying to sort it out.

 

I went back and remodeled them using lofted solids.

Seems to be working but is very slow. We'll see how it turns out tomorrow after it runs for a while on my feeble computer.
