Hi Gaieus,
I have just been experimenting and had also come to the conclusion that it may be better to work in some other (larger) unit. I only want to produce an illustration where the scale is not really an issue so I'll carry on down the route you suggested. But don't worry I'll be back with other questions I am sure

Hello Sketchupers,
for the last week or two I have been struggling to create a bathtub shape. My intention was to create a flat rounded oblong add an thin arc profile at 90 degrees and use the follow-me tool to run it around the outer path of the oblong.
Hours later I am no further as the outcome is so unpredictable it never seems to be the same twice.
I have gone back to basics and have just gone through Gaieus' excellent "Dome" tutorial to see if I had missed something. I cannot even produce a closed dome, the centre segments always seem to be missing. However after downloading some of the examples from the tutorial they seemed to work fine and produced "closed" domes. When I started from scratch and did exactly as in the tutorial... no joy. The only difference was that I was using a "mm" template and the tutorial was done in inches. When I switched to inches.. IT WORKED!!
I have attached 2 files which are identical (I think) except that one is done in mm (circle/arc dia. 12mm and 15mm) and the other is in inches (12" and 15" diam). The only obvious difference is that the "inch" dome is complete and the "mm" one has a hole at the top. Can someone check these and provide an explanation why the dome is not closed?
Thanks in advance

Hi from another Noob.
I am a mechanical engineer so am used to working with 3D CAD software. I have just gone freelance in a field not requiring a full blown CAD, but where it would be nice to produce the occasional 3D drawing to illustrate the product I am selling.
I am finding it somewhat frustrating knowing what I want to do but not yet knowing how. I do however find that it is far easier to learn something new when a specific task needs to be done rather than trying to plough through tutorials and the manual.
It looks like I may soon have to go for the "pro" version or have to learn Ruby in order to realise the full potential.
I guess there are a few long nights ahead!
regards
Tim
