Further advice well received. I will also look for the Purge plug in. I saw a post below mine that was griping about SU. Every program has its limits no matter the dollar assigned to it. Frankly after 5 years and the need for simplicity in 3D drawing I think SU has really been a great addition for the amateur world. Especially when Sketucation can come through with pleasant down to earth, straight to detail, advice like what I have just experienced. I did not mean to start anything new here. I merely mean to again (and in another way) thank those people that so enjoy the program that they are willing to offer free advice. Fords are Fords. Fords simply just don't come with Rolls Royce interiors. But, you can still have a nice ride through the countryside while in a Ford!

Thank you for the profile advice. I will immediately do that. As for the OpenGL settings - I will experiment in that area. Thanks again.

The advice re scaling up small objects before attempting to chamfer them then back down again after is golden. This nearly drove me nuts before I read it.

Whenever you experience such problems, always be suspicious of this non-planar thing. With raw (non grouped) geometry, you can always check the co-ordinates for each endpoint with the Text label tool - by default it gives these co-ordinates I also used in my example.

Like the attached file? Are other menu items grayed out as well? Coved Board.skp

Hi Dekade, hi folks. It would be easier having a look at the SKP file to see how the model is made. I suspect that your woodpieces are not separately grouped or componentised (sorry for that word). Keep in mind that, in SU, layers are not used as in CAD softwares. They do not separate geometries. They only serve to control the visibility of objects. To separate geometries, you must use groups or, for repetitive elements, components if you want to save in file size. See attached SU file for ideas. Textures and rotation.skp

Moved the thread to the Developer's forum. We have reorganized so that the Plugin section is only a list of plugins you can download and use.
