Length (and other) property changes not working

Post by Michiel »

Dear all,

I'm using FreeCAD with info:

OS: Ubuntu 16.04.6 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.4.
Build type: Release
Python version: 3.5.2
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: Dutch/Belgium (nl_BE)

I'm just new to FreeCAD and I was following a video tutorial drawing a line and then changing the length property in the lefthand side box. When I change the value and press enter, the line is not adjusted. I have the same for the heigth of a wall object for example. after a computer restart it is the same problem. What could be the cause?

Hard to say. Can you describe step by step what you are doing from opening the empty sketch?
It is normal that the line is updated only in sketcher until you close the sketch, you can force an update though with the Update button.

open freecad
icon in bar 'make new empty document'
set workbench 'Arch' in bar
icon '2-point line' in bar
click once
click twice to create the line
length value reads 1,14 m
click in the length value field
change 1,15 to 5 + ENTER

The line doesn't change its proportions in the view area.

the drawn line stays the same, but the entered value stays the entered value. It would keep showing 5 m also after unselecting and reselecting the line in the view area.

however, selecting the tool 'start enquête'and selecting the line in the viewer with it, keeps showing the original 1,14 m label.

From Draft_Line :-

The line can be edited by double clicking on the element in the tree view, or by pressing the Draft Edit button. Then you can move the points to a new position.
And

From the same page, Properties section:-

Length: (read-only) specifies the length of the segment.

Is there any way to enter a specific length?
When drawing a plan of an existing building it seems faster to me to enter the real values than to pull on the lines until you have the real length.

Use the polar entry method, don't forget to 'press R' or click the radio button for angle. There appears to be a bug otherwise.

Welcome to the forum and thanks for reporting the issue.
May I ask you if you recomputed the document (F5) after changing the length of the line in Properties?

Well, that is weird, yesterday I had exactly the same behavior as OP.
Today, no updates, but it works! :o

I did not.

Now, I have tried the recompute (ctrl+R) and then it changed the length 2 times properly after recompute. After 2 times, also this, stopped adjusting the length properly.
