I am very new at this, so please be gentle... ;)I have created a GH definition which is basically just a series of extrusions and boolDiffs.  What I'd like to do is create a button on my toolbar that prompts me to "Select First Curve," "Select Second Curve," etc. I have created the following Python script inside the Python GH component:*****import rhinoscriptsyntax as rs# Boolean Genieleft = rs.GetCurveObject("Select Left Hole")right = rs.GetCurveObject("Select Right Hole")outside =…See More

Hi all,I am trying to use GH to visualize what will happen as a rotating cutter passes through a block of material.  Attached is a simple example showing what I mean. I have seen examples of taking the rotated cutter and arraying along the path, then BoolDiff, but that leaves a very choppy result.I have seen a version where the profile was lofted, which was promising, but I need to be able to move the path curve up/down in Z without altering the vertical orientation of the cutter axis.Anyone?See More

Hi all,I somehow lost a previously-functional GH definition, and now I can't remember how I made it...  I need to be able to visualize how different router bit profiles look after traveling through solid material.  My main questions:1:  When I use RevSrf, I don't get a shaded preview for the router bit - am I doing it wrong?2:  How do I tell GH to essentially do a Sweep1 using a solid Brep as the profile instead of a crv?Attached is my clumsy start.  Any help is appreciated!Best,dhSee More

Hi all,I am using GH to create templates for making eyeglasses.  The process uses a pantograph approach for many (30+) steps.  Each stage requires us to make a template with pre-defined mounting holes.  What I'd like to do  is setup a GH definition for each step, so all I have to do is:1 - import the flat line art of the design.2 - "Set" the left/right eyeholes3 - "Set" the outside profileThen, GH would export (or sendToLayer) the appropriate curve & mounting hole combinations for each…See More
