A question about possibly un-fixing entities.

asterios_anagnostou

Hello! Firstly I'd like to say that Onshape is awesome and your tutorials have certainly helped me get started! I began building a part yesterday and just ran into a problem. Along the way I noticed that some of my lines/circles/radii were blue and some were black, but I didn't think anything of it and I didn't know how or whether or not I was causing it. Now, I'm much further into my drawing and I've run into some problems because some of the things I'd like to move, I discovered, are immovable. Now, I know this is absurd, but by way of some erratic firing of formerly unused synapses in my brain, I thought or hoped that the "fix" would fix inconsistencies or errors in the drawing. So, I selected the whole drawing and "fixed" it, lol. I was having problems even before I did this because half was fixed and half wasn't, so even if I go back a few moves in my history, it won't really help me. Is there any way to un-fix my sketch? I'm still trying to get all the entities where I want them to be and to size them properly. Thanks in advance for any help!

Asterios - hello!
This is a very general question and without a link to a document for the forum members to look at, it will be hard to answer your question.
For an introduction to sketching (and contraints), have you watched the 'intro to sketching' lesson here?

Hello!

If you want to delete the 'fix' constraints in your sketch, do the following.

First, make sure you are editing the sketch (right click your sketch feature and click 'Edit...')

Next, check the box that says "Show constraints"


Once you do that all the sketch constraints will appear on your sketch



look for the ones with the 'fix' symbol:


You can then right click on these and press "Delete sketch entity" in the context menu, or as a shortcut you can left click the constrain and then press 'Delete' or 'Backspace' on your keyboard (Mac or Windows respectively).

Hope this helps!

Thanks for both of your posts! I realized shortly after asking this question that defining a dimension also fixes the entity. Gosh this is fun. I learned so much in the last few days it's incredible! I learned two days ago that you can click on a surface and start a sketch there. Super simple, but inexplicably it escaped my notice for about a week lol. Thanks for your answers again and sorry for the late response!
