Hi Michael,

Here are some observations on v4 beta:

Copy as PDF :
When "Exporting as PDF", the objects sizes are preserved while when "Copying as PDF" they aren't.
edited :
(could be a problem with the way Affinity Photo and Affinity Designer read the PDF.
If I "Place" a previously exported PDF file into the Designer document and double
click it, it opens an "integrated window" and if I then "Paste" a copy PDF from MoI in it, the size is ok).

Copy and Export as PDF
Tick marks have the thickness of drawing lines instead of being the size of dimension lines.

Small display error when drawing solids (not specific to v4. It is really minor as the result is not affected) :
Draw a solid cube, lets say 10 x 10 x 10, starting at Origin, then, in the 3D view, start drawing another solid (or a rectangle) right "underneath" the first one, again starting at Origin. When you move the mouse to the back of the plane, it will display a negative value as long as the cursor is moved under the measurement of the bottom of the solid on top.
It doesn't cause any error if you click to fix the point. It is just indicating a minus sign in a positive area while moving the cursor.

Dimensions wish :
Would it be possible to add the Style (color) property to the Defaults as it already appears in Details?

Extrude command wish :
Not exiting the command after specifying extrusion length (would wait for right click by user).
It is similar to an earlier demand by Leonardo, but more specific to the use of options within the command.
Specially if Tapered is activated, if one enters the Extrusion Distance then press Tab, the cursor won't go to the Draft Angle text box.
If Tab is pressed, it would be possible to go back and forth Extrusion/Draft angle and only end the command on right click.

Add an Axis Show/Hide check box in the "Grid Snap" button wish :
This check box would be under the Show Grid checkbox.

Thanks again,

Michel
