Geometry Cache Broken?

It's not broken, but Geometry Cache has different behaviour depending on how it is connected.

• If it is not connected at all, a warning is displayed.
• If it is only connected at the left side, you can bake your geometry.
• If it is only connected at the right side, you can reference geometry from the Rhino document.
• If it is connected at both sides, it acts just like a regular parameter.

This information is also available in the Tooltip of the Cache object. If you disconnect your panel, it should work as expected.

Hi All,

I am not sure if I am doing something wrong.  I can not get the geometry to bake in Rhino.  I thought the component was designed to allow me to bake the geometry in Rhino, than allow me to manipulate it within Rhino, then reload the new manipulated geometry back into the GH definition and continue my definition.

I continue to get an error that indicates I have NOT given it a unique name.  It does NOT allow me to bake it to Rhino geometry so I am unable to manipulate within Rhino.  However, for some reason I am still able to re load it back into GH definition.

Thanks for any sage advice you can offer.

Hi,

just opened your file - baked to rhino - transformed - reloaded back into gh.

No errors, no messages.

Strange, here everything works exactly how its supposed to.

Are you using version 0.9.006? and Rhino5?

Thanks for trying it.

Stan

Yes, I am.

Gh 0.9.0006 & Rh 5.0  (5.1.20801.1108)

64bit.

Latest built on both.

That is exactly what I am using.  Hmmm?

Thanks again.

I have isolated the error.

If I make the wire connection BEFORE I input the Unique Name, it will never bake.  However, if I make the wire connection AFTER I input the Unique Name, it will bake.  That seems strange but that is a repeatable error.

Phillip,

Thanks again for your assistance.

This component appears to be very picky about exactly what order the connections are made.  If the process is done in any other order, I get errors.

You must first drop the geometry cache on to the canvas.  Then give it a unique name BEFORE making the connection to its predecessor.  After the predecessor connection is made then click on the bake button to create the geometry in Rhino.  Then make a copy the geometry cache component and disconnect the copy from the predecessor and connect the component to the successor component.  

I am not sure why it takes such a specific method to get this to work.  Is it just me or is it that specific for all?

OK here is an additional nuance.  When I bake from the Geometry Cache it automatically bakes to the Default layer even though I have another layer current.  I worked for a long time thinking it was not baking because I had the Default layer turned off so I was not seeing the geometry being baked to the default layer.  

It seems like it the geometry cache should bake the geometry to the current layer or at least offer the bake layer dialogue sometimes offered during conventional baking.
