New Sketch after scaling model

[ruben_van_lerberghe]

Hello everybody,

After finishing the model attached, I realized the proportions were not exactly good so I used the scale tool. 

3 times, non uniform around the X-axis.

In order to make the model however, I need to adapt the measurements of my initial sketches.  I don't see how I can figure out how these measurements have changed after scaling, for some parts. Also, it's impossible to work with a width of 32.053 for example, so I will need adjust the new measurements to rounded measurements. 

Should I restart the model and make new sketches, having copied the scaled bodies to get close to those proportions? 

Or is there an easier way out ?

Thank you so much

The usual process is to dimension and otherwise fully define your dimensions - and then simply edit dimensions as needed.  (The parametric dimensions "drive" the model.)

If you run Utility>Compute All  (Ctrl B on Windows) does Fusion return any Warnings of unresolved issues?

Hi,

In addition to @TheCADWhisperer's suggestion to dimension the sketches, I suggest working with user parameters.

In this way, you assign the name "height" to dimensions such as d777 for a better understanding.

That works for the "hard" parts, but for anything containing a spline, it's less straight forward.

Thanks but I don't think I understand ( this is the first model I made and already had help here on the forum)

I need to have all my sketches fully constraint but I do have dimensions ( for example the seat and back).

Now if I go back and edit those dimensions I don't have the scaled model as a guide. 

Or do you mean in a new model ? 

When I do 'compute all' it gives me the yellow warning, for the Surface Stitch : Reference failure / Stitch result body is invalid. 

I don't get that resolved..

Thank you,

But for a model like this one, does it make sense to build it with user parameters?  There aren't really constant measurements..

I believe that is a bug and have tried to bring it to the developer's attention on the EE forum. I am not sure the message has been received. There are really only 2 people left who still participate regularly. @Phil.E and @jeff_strater.

Ok thanks.

And is the conclusion on this topic that it's best to start a new model ? 

And if I do, and I want the sketches to be fully constraint, how does that work for a spline. Fix every point ( also the green ones)?

Thank you

Thanks for the notice @TrippyLighting .

The problem is with Stitch. The input surfaces are causing some trouble. 

If you replace the stitch with a boundary fill operation it works better, but there are some more reference failures down the timeline because that necessarily creates a new body. A little more editing is required to reconnect the downstream references.

This can be logged for the stitch command. Thanks!
