Sizes and positions change uncontrollably

klaus_krämer

A picture tells more than thousand words:

This happens, when I add a text and subsequently add a midpoint constraint:

Before:

After:


You see, the text has increased its size significantly without any real purpose. Similar things happen to dimensionings in sketches which sometimes simply become unreadble unless the are manually repositioned. The latter gets annoying when sketches are parameterized.

Is there any way to switch this unwanted behaviour off?

Put a dimension on the text box, either horizontally or vertically to constrain the text to a particular size

@GWS50 That's not my problem. It's any uncontrolled change of size or position of elements! What has a midpoint constraint to do with the size of the element i add the constraint? Nil - as long as there are no other constraints. That's bothering me.

Someone with more knowledge than me will be able to help you! 😀

The first constraint (which would drive a change in size) or dimension you add to any sketch will scale the sketch. This can be a great feature or a frustration. Typically, where it's very useful is in importing a sketch from a DXF.

In this case, if you add a dimension first, and then the mid-point, you won't have the issue of the size jumping. You could always delete the dimension after that.

Hey guys, don't get me wrong: The simple question I've asked, was if its possible to switch this behaviour off, not about workarounds. Thank you anyway for trying 👍

Nope. There's no option to turn it off. You could create an improvement request.

It’s just solving based on the top left anchor point of the text. If you don’t fully constrain, things will move.

This is a feature not a bug. The 'behaviour' follows the same logic as all sketch elements: To define the size, and keep it when constraining to other sketch elements, just dimension it and you're good to go. We do that all the time with all the entities we find in sketches.

Thanks @S1mon, that's, what I was asking (but not really hoping for). 🙂

In this case, you could also use the sketch transform tool to move the text into the right position. In sketcher, select all the sketch entities, pick the transform tool, move the transform reference to the center of the line you want to align, drag the text until it snaps to the correct position, select the origin (or whatever reference) and the vertical line, and add a mid-point constraint.

This won't change the size.

That's really something i hadn't been thinking about - thanks!
