Thanks JGA
I do have a custom folder called "My materials", but I did try emptying it to no avail and I do have some long threads (large components I created) within my drawings. I will try deleting the folder altogether and re-create a new one and experiment with removing the components. I will Let you know how I get on. Thanks for the advice on the small icons as well..... just totally missed the obvious. 
Hi
I have both Sketchup 2014 pro and 2015 pro. I have discovered a common issue for both versions which is as follows.
If I have the Materials window open and try to load save or even start a new drawing, Sketchup takes 40 seconds or so to respond (even when loading the most simple of all models). If I close the Materials window, then Sketchup loads and saves instantly. I have my own favourite folder of materials which I removed but this made no difference at all.
If anyone has had this issue and knows the answer to it I would love to know.
One other thing, can anyone tell me how I set the material icons to a smaller size (I've done it on 2014 but cannot remember how I managed it)
Thanks

Thanks Dave
I've only just had notification of your reply, I've bought SU Podium and what you say is pretty much the case, I like your idea of having a LEM as a background

Hi
I have drawn a parcel box in SU Pro, the colour is black. I know little about rendering, all I want to do is create a good clear picture of just the object, no scenery, background etc. It needs lighting (as it is black). Can anyone suggest a simple to use rendering program that will easily create a decent image with a totaly white background (maybe just a drop shadow but no more). Everything I come across seems to concentrate on outside buildings etc. I have Renditioner Pro but this doesnt seem to give me the result I am looking for.
Can anyone help please
Hi
Does anyone know of a simple plug in for filleting to joining lines. I would like to select the lines then be prompted for the size of the fillet.
Thanks
