Worksession | Rhino 3-D modeling

The Worksession command manages a list of models that are being used as reference geometry.

Note

●

The Worksession command lets more than one user work on a large project. By breaking the project down into many files, one user can edit a part of the project while another user edits a different file. Only one user can have a file open for editing, but many users can see it.

●

The attached file can be in any format that Rhino can import, not just Rhino models. Attached geometry cannot be edited (for example, Move, Scale), but it can be used for input to creation commands (for example, Copy, ExtrudeCrv).

●

When a worksession object is dragged, it snaps back into place.

●

Each user maintains his own worksession (.rws) file. These are not meant to be shared. The Rhino files used as reference geometry are shared, but the .rws files are not.

●

Worksessions cannot be used as layout elements.

●

Objects can be copied from a worksession file and pasted into the active file.

●

For a description of the process Rhino 5.0 uses to locate files used by worksessions and linked instance definitions, see Rhino Wiki: File finding.

The attached file geometry appears on a unique set of layers under a parent layer with the name of the attached file, and the attached file layers as sub-layers of the parent.

You can change the layer state of reference layers (Color, On/Off, Locked, Print Color, Print Width, Linetype), but you cannot add new layers to or delete layers from the attached file. The list of attached files are not saved in the current model file, but are saved in the worksession file (.rws).

Steps

In the Worksession Manager dialog box, click Attach.

Select files to attach.

To save the worksession for future use, click Save or Save As.

The current worksession name appears in the dialog box title.

●

Your current model closes. You are prompted to save changes.

●

Your current worksession is cleared.

●

The files listed in the worksession file are opened. The active file is open for editing and the others are attached for reference.

●

The layer states for the files are set.

●

The Undo command has no affect on worksession actions.

Displays the locked/unlocked status of the attached files. A tooltip on the lock icon shows information about who has the file open.

The current model closes and becomes an attached model. You are prompted to save changes in the currently active model.

Displays the locked/unlocked status of the attached files and information about who has the file open.

LimitReferenceModel

The LimitReferenceModel command limits the amount of reference geometry that is available to work on by purging the reference geometry that is not needed in the area of interest.

This can make Rhino's display more responsive or simply cull unwanted visual clutter.

Steps

Draw a crossing sphere that defines the area of interest.

Objects not enclosed or touched by the sphere will be purged from memory.

For models with previously applied limits, reloads the current worksession file, restoring the purged objects.

PurgeRefObjects

The PurgeRefObjects command deletes selected worksession reference objects from Rhino.

Note: This command is useful for hiding unwanted worksession geometry during the work session.

Warning: The Undo command does not work for the PurgeRefObjects command. To recover the purged objects, activate another attached file or click Refresh All in the Worksession Manager dialog to reload the worksession model.
