Easier way to move around viewports?

This may seem silly, but it's driving me nuts.

I'm looking for a more reliable way to navigate around the viewports in constructor.

For example I'm building a house, and I want to zoom in on a particular face in perspective view that I made while in top view. I go to perspective and try to zoom, pan, right click and w,a,s,d, or pretty much any option to move around, and most times wind up clear on the other side of the blueprints I'm working from.

Then I have to zoom back out, click on a brush somewhere in top view so I can find where I was, then HOPE I get lucky trying to zoom and rotate back like I wanted.

If I just want to rotate in perspective and mess with an object, a face for example, I have to do a HUGE rotate and then zoom back in, hoping it doesn't do a massive jump somewhere under the object. Is there a way to rotate the camera in place?

It's not video lag I would hope, I'm using 3ds max to model smaller things (chairs, tables, etc), and I am able to zoom, pan, rotate, etc without warping clear across, under, above, or wherever.

Is there a way to do a walkthrough in constructor, walk around at ground level or set a height to move the camera around. Or possibly move in smaller increments, so while I am moving around trying to apply textures I don't jump through the entire building?

I am finding constructor quite useful, with the exception of being able to precisely position the camera with any amount of reliability. If I do manage to get angled at what I need, it is sheer luck.


These are the keys I use.

Press and hold Scroll Wheel on Mouse to Pan

Press and hold Right Click to rotate.

Press and hold Right Click, then use W,A,S, and/or D to fly around. Pressing SHIFT to fly about more rapidly.

Are there any other keys that allow for a more precise, up close camera positioning?
