All measurements are in mm

I've been trying to replicate a drawing robot by 'Evil Mad Scientist' with wooden ends instead of acrylic before I attempt to cut it in acrylic. I can constantly mess it up and it wont cost me anything as I have quite a bit of birch ply knocking around. When I've worked it out and cut half a dozen I'll do it in acrylic.

The 2 ends are 80.0mm wide and 60.0mm high

There are 2 holes (8mm in diameter) equally spaced at the top so the right inside edge of the hole is 5mm from the right hand side and the top of the inside hole 8mm from the top side. The left hole is the same measurement's from the left hand side and top.

I'm not sure how to get the guide lines into position so I can align the holes up correctly.

Its probably dead simple, but I'd rather someone show me how its done than waist hours trying to get it right.

Thanki's a lot.

Double click on a guide and it will allow precise positioning in absolute or relative values.

If you double-click on a guide, a small dialog opens which allows you to position it precisely (or relatively, if you prefer that).

Or else, the guides are snappable, so you can snap them to something. And they can also be snap targets, where you can snap other things to them.

Here's the manual info on Snapping, and if you read on below, is info about Guides: http://tavmjong.free.fr/INKSCAPE/MANUAL ... pping.html

Edit
Well, TD posted while I was typing. But I'll post anyway, since I've included a link to the manual.

Thanks lads

I looked at the manual (I bought it a couple of years ago) but couldn't understand the guide or snapping concept. I'm not thick, but old age plays a big part here and things that used to take a few minutes now take considerably longer.

When you double click on the horizontal guide does it measure from the side of the rectangle or from the side of the work area.

Also I've gone back into Inkscape this morning and opened the most recent from last night, but when I drag the horizontal guide in any direction the measurement box at the top doesn't move so I can't figure out where the guide should be.

Sorry for being a pain, but I've only started to use Inkscape again since my CNC Router is up and running and I need to get a firm grip on how things work here if I'm to get any designs and cutting done in the near future.

Thanks a lot.

An easier approach might be to duplicate the rectangle in-place (select it and press CTRL-D) then use Object > Objects to Guides to automatically create guides that follow the edges of the rectangle. You can then double-click on a guide and set a relative offset to move it to where you need it.

(An alternative to using the Relative Change checkbox is to leave it unchecked and just do some maths directly in the X and Y spinboxes in the guides dialog - i.e. append "+5" or "-8" or whatever you need, then when you tab out of the box, the calculation will be done for you)

Snapping works differently since Inkscape 0.91 than is described in the manual (esp. when you've got an old version).

Currently, this is how snapping works:

You can see the current coordinates of the mouse pointer in the lower right corner.

Or you just create an object (e.g. a rectangle) that has its width set to the distance you need, and align that with the main rectangle, then align your hole with that object.
