Thank you GreyHead. All is explained! Works fine now. This shows how important it is to observe the clues from the inference engine.

Thank you but can someone explain why the second opening took more work? Why did it not work as easily as the first one?

Hi Pagan
Thanks but my computer cannot download this film, despite my adding plugins. Is it on YouTube by any chance?

Hi Gaieus
Thanks for the tip. However;
The window does not work but the door does. This is consistent whatever I do. All faces are parallel.
Thanks again,
Molly

I've also altered my preferences to alert me when someone posts a reply but this is not working. Any ideas?

Thanks Guys
I guess this is just a quirk. I knew how to get what I wanted but I was concerned that SU wasn't doing what it was told!

All the best
Molly

Hi Guys
I've a strange situation. Briefly, the push-pull tool does not work according to the information. And I really think its to do with my Mac. A picture is worth a thousand words so...
I created a rectangle, pulled it up into a wall, used the rectangle again on a face and push-pulled it through. I know I should get a hole but as you can see, I do not! All faces are parallel of course.
Any suggestions? Actually, I think my whole program is flawed throughout. Just the simplest things are difficult. Such as my ongoing selection problem which is driving me up the wall!
Anyhoo, hope somebody can shed some light on this.
Thanks
Molly

Meant to mention; of course I have a fairly detailed model now. Any tips of how to separate it all into easy layers? I suspect I will have to start from the beginging because of my ongoing selection problem.

Molly

Thank you Alan and Gaieus. Certainly lots more to absorb yet! Thank goodness for video tutorials.

Thank you Remus. Nice link by the way. I'll look into that.

Thank you Gaieus too. No, I don't know about the glue feature. I'll look that up. And layers too. That does seem a way out of the complexity issue.

Hello everyone,
A challenge for me. My model has now become so complicated (and I haven't even got around to modeling the castellations) that when I paste, (for instance) a window, it is 'snapping' to every line, corner and guide except for the one I want! Things are complicated by the fact that some of the walls of this building are not aligned with the axes. This is probably what I meant by my earlier post when I mentioned that I wish the Inference engine had an off button. I'm using x-ray, all the views and magnification but just getting to move the window in and out a fraction is proving tiresome. I'm making guides, deleting guides, rotating, resizing, you name it and getting thoroughly confused. There has to be a better way I'm sure!
A slightly different problem is that, bringing in a model using paste, seems to align it to a different axes to that window that created it. Is there a way around this too? I've had some fun changing the axes! (not!)
Also, would anyone know, in this Forum, is there a place to tell it, to inform a user via e-mail when a post has been responded to?
Best wishes for now and thanks in advance,

Molly
