Hi there,

I’m trying to figure out how to synchronise a left and front view so objects appear the same pixel size. This is useful for raytrace rendering with viewcapture to file.

I just zoomed on this object

And also the same object from a side view;

but they appear different sizes.

How can I make them the same zoom level?

Best,  
Jeremy

Rhino has a one-shot command `_SynchronizeViews` which should make all the zoom levels the same in the parallel viewports.

[https://docs.mcneel.com/rhino/7/help/en-us/index.htm#commands/synchronizeviews.htm?Highlight=sync](https://docs.mcneel.com/rhino/7/help/en-us/index.htm#commands/synchronizeviews.htm?Highlight=sync)

You can also toggle the use of linked viewports - in which case all parallel viewports zoom simultaneously at the same zoom level when you zoom in one of them. This is the macro:

`'-_Options _View _LinkedViewports _Enter _Enter`

The button is here:  
LMB is `'_SynchronizeViews`, RMB is toggle linked viewports:
