How to resize without redrawing

This cabinet design is 4'6" wide. I want to change it to 4'10" wide, adding 2" to each side. Is there an easy way to make that change without having to redraw both sides manually?

I am new to QCAD, all CAD for that matter, so please use small words.

Lastest version of QCAD. Win 11

TIA

Yes. I would use the "Stretch" tool.

If you master the stretch tool then the modification of your cabinet is a piece of cake in Qcad ...

Thanks. I figured it was that tool, but I couldn't make it work. Hopefully the link you sent will help.

Remark that in the tool reference, step 2 under 'Usage' is indicated as point 1 in the example under 'Description'.
Step 3 = 2, 4=3 and so on.
Omitted but for step 6 (=5) one can also key-in the target coordinate on the command Line.

# EDIT # The figure will be adapted shortly
(See: https://github.com/qcad/qcad/commit/98b ... aaee9baab1)

The idea is to draw a selection box around all what must be moved, crossing all what must be modified partially.
Without or with a selection to filter on intended entities.
Then indicate how that must be stretched with a reference point an a new target point for that particular reference point.

You are virtually free in what to select as reference and target.
2 grid points horizontally 2" apart in the intended direction would already be fine here, any grid point will do.
Or any point as reference and then entering '@-2.0,0.0' or '@2.0,0.0' in the command line for relative (=@) 2 units left or 2 units right works too.
(Enter text without quotation marks, the decimal parts are not required here, the list and the decimal separator are by application preference)
Or you already have some snappable target point to join shapes side by side for example.
There are thus several ways to accomplish this.

...one can also key-in the target coordinate on the command Line.

My grid is set up in inches, and since I was stretching in whole inches, I manually stretched my selections two grid marks left and right respectively. I am going to experiment with what you suggested. It would allow accuracy when stretching fractions of an inch. Thanks

I manually stretched my selections two grid marks left and right respectively. I am going to experiment with what you suggested.

Also meaning that stretching was managed ... Great .

@-2.0,0.0 with the '@' for relative is relative to the QCAD relative position.
Usually the last indicated coordinate or that entered in the Command Line.
It appears as a little crossed red circle that tends to hop around with every new coordinate.

Apart from relative there is also absolute '-2.0,0.0', absolute polar '12.0<45' and relative polar '@12.0<45'.
Absolute is then in relation to the drawing origin ... Point (0.0, 0.0)

If all else fails, in not so trivial cases one can define a line segment that is limited/trimmed to the required translation.
Then the original reference is the start point while the target is the end point, both with snapping to the ends of the line segment.
The segment can be deleted afterwards.

I can't figure out how to see the place where you can add in values for how far you want to stretch something. I've searched for videoes, and found one from a previous version of QCAD that showed number values right by the cursor when in stretch mode. I don't know if that is still a feature, but it would be great.
This is the video I found. She talks about stretching by displacement starting around 3:35

Thanks for helping.

Hi,
For the coordinate values near your cursor hit the F8 key, that toggles between 4 displaying methods.

For entering coordinates see the line under your Command History, the Command Line.
If that is not showing refer to menu View .. Command Line (GM).

'GM' is the shortcut key sequence, simply hit the 'G' key, release and hit the 'M' key shortly after that.

Hitting the space-bar sets the focus on the Command Line.
One can immediately start typing after that.

The video is about QuickCAD developed by Autodesk. Don't use it as tutorial to learn how things work in Qcad developed by Ripponsoft. It is a different app!!!

Missing something that obvious can sure make a person feel dum.
