Trouble editing a sketch

[scampa123]

In my sketch I created a rectangle that was built off of a center point.  So I assume that is a constraint...

im trying to figure out how to edit the rectangle, but I cannot make it work...

Basically I want to raise the bottom of the rectangle... This ultimately revises the rectangle, which I could do with a dimension.. But I no longer want it to be built off the he center point and resize in relation to that point... I simply want to hold its current position and move the bottom of the rectangle up 2mm.  I assume this has to do with some constraints on the rectangle but I need help understanding ho to achieve this.

thanks!!

I think you can find the answer in this post,  I did 😉 Not for the same reason but I think you can use the finger trick as well

Sorry. filter not finger...

you can also just delete the construction geometry that is making the rectangle a "center point rectangle".  Then,  you can do what you want with it, either with drag or with dimensions.

Here's a screencast:

I'm still having issues moving the bottom of the rectangle....

I created a sreencast to show what I am doing...I'm on a Mac, so maybe I need to hold a key or something??

Thanks for the help on this!

Have you tried to delete every constraints as I should justed from the filtering ?  Then you can make the constraints yourself after words

I would check your selection filter. That is the only way I could reproduce happening in your video. Other wise what you are doing should work and you definately don't need to delte the construction lines that define the center to resize the rectangle.

Hope that helps!

How do I delete the constraints? Which icons are the constraints?

What should my selection filter be?

whats the video in my first reply "link"   ;-D

filter = sketch geometry constraineds.

drag select all and delete.

and focurse remember to turn ALL on afterwords

I would leave it on select all until you have a reason to be specific. It can come in realy handy to only felter selection to certain types of geometry some times but I leave mine on select all 90% of the time.

I'm not sure what I did, or what changed..but now I can move the bottom or top in my simple sketch and the rectangle does not move (except for the side I want to modify)

When I try this in my overall project, I actually move the whole rectange rather than moving one edge of it...Again, I cannot figure out why!

I apologize if you feel it's already been answered, but I'm struggling here!

[jeff_strater]

The problem in your overall project is that you have the rectangle dimensioned.

You have specified that this rectangle be exactly 67.1 x 111.13.  So, when you move one of the lines, Fusion has to keep those constraints.  The only way to do that is to move the whole rectangle.

So, in summary:  If you want to move just one side of a center point rectangle:

1. delete the construction lines in the middle

2. remove any dimensions that are constraining the rectangle's size

Given all this, I would actually recommend just using a two-point rectangle to begin with.  If you are going to modify it, I wouldn't start with a center point rectangle - that form is designed to create rectangles that are constrained to stay centered in a certain spot.

If you haven't seen thsi video I would definately watch it. It really gives you a nice explination of sketch strategy with constaraints and dimensions. https://youtu.be/OtkmiPeUxqE

Thanks Jeff! I started with the center point rectangle because I wanted it centered to begin with..Once I printed my object, I noticed the hole was slightly off at the bottom, so I only wanted to raise the bottom to compensate. This is a case for a 5" screen that has not frame for protection....

Thanks again!

Thanks Joezisa!

I'll definitely watch it! I've been trying to watch allot of YouTube videos on using Fusion360, I'll add this to the list!
