FS#2283 - Add a "Select Similar " command

As a heavy mechanical drawings user, it would help a lot to have an option to select similar entities while working on QCAD.

In the flow of the work, sometimes I need to make some changes in all similar entities of the drawing.

The Select Similar works selecting all the same items with the same layer on the drawing.


I have a drawing for other company and I have to make a massive layer changing to my own layers.

I select a line and circles with a box selection, activate the Select Similar command and the QCAD instantly selects all lines and circles(no matter length) with that same layer. I can then change the layer of all of them instantly.

Or if I have a peace with a lot of circles, that aren’t in a block, in one time I want to change the layer or diameter of all circles in a certain part of the drawing.

I select the circle and activate the Select Similar command, the QCAD automatically selects all circles with the same layer and I deselect the circles that I don’t want with a box desselection and change the layers of them, or the diameter via properties.. and etc.

There is a workaround, that would be working with activating or deactivating layers, but the select similar would be a faster shortcut.

Thanks Andrew and team!

Additionally one can select all entities of a layer with +Y, deselect with -Y.

How that works:
- Without a selection right click on the layer in the Layer List.
- Select the option Select Layer Entities (+Y)

Remark that +Y adds entities to an existing selection and -Y removes entities from the selection.

Thank you, Andrew and CVH.

I haven't tried yet, but with your description these commands can produce the same effect of a "select similar".

ASAP I'll test and write here the results.

Thank you,

Dear CHV and Andrew,

The informed commands work as agile as a select similar command.

Thanks for the support, and my apologies for not knowing those commands before and take your time.

Best Regards,
