Increase the height of this object,

[allelopath]

I want to increase the height of this object, say to 12"

How to do this? I don't see the dimensions in the properties.

Hi,

SOLIDHIST set to 1 is used to store History on new 3D Solide created. For those created before, you have to modify its history by OPM.

Once you've done it for elementary Solide (box, sphere...) you can apply boolean operation (union, substraction...)

And new complex Solid has history property  set to Record, so you can go back to base Solid to change their dimensions. But if History is set to none on base 3D Solid before boolean, or after boolean you lose all possibility to modify original dimensions. It's dead.

On your solid #3, it's dead beacause history is not stored, but if you copy your solid #2, change history property, and apply substraction, you can select each original box (with Ctrl key + clic) and apply new height in OPM. See video under.

@O_Eckmann. Thanks for the video. I follow it so:

Draw Box 1
Change History of Box 1 to Record
Draw Box 2 (be sure to set height to a value larger than any height you will want)
Change History of Box 2 to Record
Subtract Box 2 from Box 1

Ctrl-click and select top face of object

Change height by moving mouse

The only thing missing now is that in the last step I would like to set the height by typing in a number.

Hi @allelopath 

Hmmmm.......You should recreate your you object so it behaves correctly.  Image-1

1. EXTRUDE command=>Select 1x1 Green object=>Enter=>10=>Enter (Image-1)
2. EXTRUDE command=>Select 2x2 Red object=>Enter=>4=>Enter (Image-1)
3.  SUBTRACT command=>Select 2x2 fat object=>Enter=>Select 1x1 skinny object=>Enter (Image-2)
4. PRESSPULL command=>Select the top surface & move cursor (Image-3)

Are the red and green objects polylines?

[ChicagoLooper]

Yes. They’re closed polylines created using RECTANGLE command.
