[solved] Drawing using Decimal foot as format

[Stan808]

Win 11
Qcad 3.28.1.0

Unable to draw rectangle using decimal foot format.

1. Have selected "Foot" as drawing unit (Drawing preference)
2. Selected "Decimal" as format (Dimension Settings)
3. Selected Rectangle with Size (RS)

When I enter 1 I get one inch.
When I enter 1' I get a foot
When I enter 1.5 I get one and a half inch, not a foot and a half (18")
When I enter 1.5' I get an error message.

Since I selected "Foot" as my drawing unit, why am I getting inches in my drawing?
I'm trying to create a drawing all in decimal Foot.

Thanks for any help.

Hi Stan - welcome to the QCAD community.

1. Have selected "Foot" as drawing unit (Drawing preference)
2. Selected "Decimal" as format (Dimension Settings)
3. Selected Rectangle with Size (RS)

With those settings all values are in foot. If you additional use common unit abbreviation like ' or " it will be ignored or you get an error message.
With other words ...
you type in 1 - you get one foot,
you write in 1.5 - you get 1.5 foot,
you write in 1.5" - you get 1.5 foot,

Anyway - if you need to switch in one and the same drawing between units you can convert the drawing with Convert Drawing (CU) below Menu/Edit.
If you convert your Foot drawing to an inch drawing all input will be from now on in inch. BTW - all existing entities are properly converted accordingly to the changed unit.
To get now a 1.5 foot line you need to punch in 18 what is then in inch and equal to 1.5 foot.

Stan,

When I enter 1 I get one inch.
When I enter 1.5 I get one and a half inch, not a foot and a half (18")

Can't be right, the drawing is in plain units and a unit is called 'a foot' with your settings.
Basically a drawing has no unit ... The rules are unit-less and are expressed in the drawing unit.
If something is 12 units long it is 12mm on a mm drawing but simply changing the unit to km makes it 12km.

When I enter 1' I get a foot.

With 1' I get 12 feet what looks weird to me.
1' 1" then returns 13 feet ...
It will accept 1" but that will result in 1 foot.
For 1.5' I also get an error saying that 1. is not a function.

Remark that most input fields can do calculations.
With a drawing in inch 1.5*12 would mean 1.5 foot.

Additionally: 1' 1" in an ich drawing is correct ... 13 inch

Thanks.

I thought a unit designation during input would supercede general unit selection.

Now knowing that the drawing itself is unitless and using units at input has no effect has cleared up my misunderstanding.

Qcad is an excellent program. Glad I found it.

No, but there is something funny ... Not quite right.

With 1' I get 12 feet what looks weird to me.
1' 1" then returns 13 feet ...

I can reproduce that on a mm drawing:
With 1' I get 12 mm, 1' 1" then returns 13 mm ...

Meaning that the foot abbreviation triggers 'times 12' in any case.

I can reproduce that on a mm drawing:

Could reproduce this in any drawing unit.
