Cannot make scaling work (CloneConvert.FCMacro) for KiCad StepUp

[sjb]

Hi All,

I can't get scaling to work (required for "Kicad StepUp WB"). The "Draft Clone" tool only allows 2dp of accuracy, so I tried to install "CloneConvert" with the addons Manger --> "Unable to fetch the code for this macro".

Then I tried using "Create Macro", and pasted the code from here
https://www.freecadweb.org/wiki/index.p ... oneConvert
Finally add the macro via "Tools -> Customize".

I cannot make the macro "run". I opened an STL file, selected all the components, selected "CloneConvert.FCMacro" then used "Execute Macro".
Nothing happens, no dialog box.

The clone doesn't scale to some dp, it is a factor. You can increase the precision if you increase the number of decimals in Preferences->General->Units->Number of decimals.

Hi Stephen, what are you trying to achieve with scaling? Why are you saying StepUp needs a scaling? (PS I'm the StepUp author)

hi

for use CloneConvert you must Part_ConvertToSolid (Part > ConvertToSolid) and Part_RefineShape (Part > RefineShape)

(1) Many thanks for that information Chris

(2) Mario - When I tried to load the board, I got the message
"error: reset values of scale to (x y z 1 1 1)"

Now a new problem...

I select all model components ready for export, then Draft Clone delselects everything.

So, I re-select all (but the draft clone scaling dialog then disappears).

I tried select all, then changed scaling, then re-select all --> File Export. Nothing is scaled though.

Please have a look at kicad StepUp cheat sheet for some basic how-to with StepUp workflow...

You really don't need to scale anything using clone or similar... The tools can do it for you automatically... Just design everything in 1:1 scale

I am using the 3D files supplied by the manufacturer (eg Amphenol/FCI, Wurth, Molex...etc)

These are typically the wrong scaling for KiCad

All manufacturer 3D STEP models are scaled 1:1
If you use StepUp to align the model to your footprint and to export the 3D model, StepUp will scale directly the WRL as required by KiCAD without having to do it manually...
