I have a problem that causes me problems when changing the dimensions of a shape.
The problem is when I change or enter a size, Freecad changes the shape exactly as in the picture.
What is the solution?

Re: Entering the dimensions changes the shape Sketcher
Hello,
If you set a dimension constraint it will modify the sketch, but as example if you dimension a line that has other constraints, change is propagated and if you have not carefully done the constraints strange thing may happen, and your case are happening.
To get more help please read:
http://forum.freecadweb.org/viewtopic.php?f=3&t=2264
and post the required informations, and if you post an example file were the "strange behaviour" occur maybe some "skilled helper" could find the culprit.
For sketcher there are a very good introduction made by @chrisb:

Where you will find more detailed explanation.

File ?
The sketch solver find a mathematical solution for your constraints. Perhaps it's not YOUR solution.
Try to modify your form (with constraints or not) with small steps.

Re: Entering the dimensions changes the shape Sketcher
so in your 2nd picture if you sel the bottom left point you could give it a dim of 302 and the figure would look like you wanted it. sorry if you already know this.
