It's ok - found the solution - hold control and measure/resize works ok.

I often import a graphic of a floorplan from a client or forum member. I find a long measurement and measure it using the measure tool - I then type the actual measurement into the lower right input window and it asks me if I'd like to resize the model, I say yes and it resizes the graphic so all measurements are to that new scale.

It now creates a guideline along the axis of the measurement.

Why has this feature disappeared in version 2017, it's a very important feature I use regularly.

works for me in windows version

Yes Dave - but you have to open separate sketchup programs - you can't just be on the one open sketchup and load another and have them both in the one open version and switch between the two.

I would like the Windows version to have 2 or more files open at once - I gather the Mac version already has this feature.

I've been using 2017 (Windows) for a few days now and I love it. They've fixed the export dwg problem I had with 2016 which meant using Version 8 for that process which I've now uninstalled.
My simple extensions loaded perfectly as I'd kept the .rbz files and just selected them. I've got my sections hide/show tab back as it had disappeared in 2016 - I loaded my shortcuts from 2016 and it purrs along nicely - all my tabs sit nicely and consistently ( I have them on my laptop screen (Toshiba Satellite P70) and work on my large screen.)

In my humble opinion this is the best Version of Sketchup so far and I've come from Version 4.

thank you Trimble

I'm on Windows and Extension Manager is in the Windows drop down.

I've finally solved the problem with the kind help of Sketchup support.
It was hardware acceleration that was causing the problem that disappeared when I disabled hardware acceleration.

Thank you Ty.

Thank you phacot - i don't have that option in windows - either 2d graphic or section cut. These are 2D graphics.

I might add - someone has changed the drop down menus and stuck them into one folder. I use two screens and have the program in one screen and the drop down menus on the other screen all open and lined up.

It appears I can't do that anymore!
