Make2D Error

Rhino Rhino for Windows

Hi,

Can anyone advise me regarding a Make2D error/ issue I seem to be getting?

I’ve got 2 files each with 2 objects I’m running Make2D on. They’re all relatively simple objects and nicely aligned in a rectangular fashion. But, in one file where Make2D functions just great, the other file (attached here) I’m getting an error where the object looks like it’s bent or skewed - though it doesn’t happen in the other two views.

As you can see in the view below the perspective (in both files), it looks an s though the foreground and background ends of the tubes I’ve drawn are offset from each other - skewed.

To double check my drawing competency, I drew some vertical lines off of 2 CPlanes and everything in 3D lines up. So, it doesn’t look like I’ve skewed the 3D object while building.

I read that Make2D is a bit finicky and I’m not sure if it’s just a case of repositioning my perspective view or if there’s just a better view to start with other than something that looks about right in “Perspective”. But, another file with objects just as simple turned out just great, and I’m not sure what I’ve missed if anything.

Make2D setting also attached.

Cheers

Hi Ken -

In Rhino, the parallel views that are created by Make2D are not based on the view in the perspective view. When you ask for a 4-view output, the command simply takes the state of the 4 viewport that exist in the document. If you, e.g. use CloseViewport to only have 3 viewports available, the command will, internally, create a 4th viewport from factory-default settings.

When I opened your file, I immediately saw that there isn’t a visible grid in the Right viewport.

When you run, e.g., the Rectangle command, you’ll see that the construction plane in this view is not as expected.

When you zoom in onto the geometry in that viewport, you will see that the object is skewed.

The Make2D command simply takes this viewport and creates a view based on its state.

To get what you want, run the 4View command to reset the CPlanes and views in all 4 views. Then run Make2D.

Brilliant! Thanks for the quick and thorough replay and explanation. Clarified a few other things as well!
