Hmm thanks TIG, i'm going to look into that. Quintus

@qverburg said: Hmm the thickning trick seems to work. Alltough it is quite a work around and hard to fix. In my script the inner lattice can be smaller than the outer ring. Thats why I create them seperately. I attached a SKP where you can see the procedure and another "error" I get in certain union situations. Would be great if you can shine a light on it Classic, forgot the attachment! union error 2

You have some very small skinny 'shard' faces in there that are causing SU to generate incorrect surface normals, hence the different shading using Sun. These typically get created when performing booleans and such. Also look for t-junctions that will cause cracking. Adam

There has been several discussions on this on the Thea forum http://www.thearender.com/forum/viewtopic.php?p=20399#p20399. Apparently it is called letterboxing. There are a couple of code snippets in the above link that can be typed into the console. I know they work for the .skp files I use in for rendering in Thea, I think they may work for files created by another exporter as well, but it may take a ruby guru to verify this.

Use an inputpoint to get all the SketchUp inference points. This is a bare-bones code snippet that will make a tool, use an inputpoint and then draw that inputpoint to the screen. ` class SUC_IP_POINT def activate @ip1 = Sketchup::InputPoint.new end def onMouseMove(flags, x, y, view) @ip1 = view.inputpoint x,y view.invalidate end def draw(view) @ip1.draw view end end Sketchup.active_model.select_tool(SUC_IP_POINT.new)` So check that out, see if it helps.

You might just try and keep the state of the control in your own Js variable, and then use onclick or onchange events to toggle the variable ON/OFF value. I do it for 'toggle buttons' such as buttons that collapse / uncollapse a <DIV>.

@adamb said: I've always used Sketchup.active_model.tools.pop_tool so it returns to whatever you had before rather than forcing the use of SelectionTool. Adam Do yo have to use Sketchup.active_model.tools.push_tool to activate the tool then? Because I tried Sketchup.active_model.tools.pop_tool when I had activated the tool using Sketchup.active_model.tools.select_tool - and that did not seem to do anything.
