No the annoying thing with 1) is that the result files are also in the scales system. What unit system do you use in FreeCAD usually? So you have two choices:ġ) Scale the mesh by 1e-3 and use SI units.Ģ) Do not scale and use units where length is given also in "mm". may need to be given if you don't want to use SI units (none of these are needed for elasticity).įreeCAD operates on "mm" by default. So permeability of vacuum, stefan boltzmann constant, unit charge etc. Some natural constants also have default values given in SI units.
So you need to provide consistent unit system yourself. This doesn't explain why it doesn't refresh.Elmer does not keep track of any units. If you then set it to Custom, Scale is editable again.Īt this point it is in a consistent state, logic being: Page -> Scale =1, non editable Custom-> scale = user defined, editable.Īutomatic does nothing here (weekly up to date) If you set the Scale Type to something else, then set it back to Page, the Scale is no longer editable, and reset to 1. Scale Type / Page (the default mode) looks like it wants to ignore the Scale value, but by default, the Scale edit is set to Editable. So I dug a little bit into this (not the source code), and it seems like TechDraw/View is made (instanced) into an inconsistent state: Such is nonsense, changing parameters, or at least being able to do so, is the entire point of FC. That said, FC is a parametric modeler therefore, don't let others tell you that you should not change parametric values. So it could be a bit before I can address the Rotation parameter. The latest stable version simply refuses to properly load Tech Draw pages and Spreadsheets.
FREECAD SCALE UPDATE
Currently, I am having a great deal of trouble with a recent update to FC, and sadly, Tech Draw is one of those trouble children. Living in Canada, a great many of my clients insist upon imperial.Īs for rotation, I have not had need of that feature, so at the moment cannot speak to how it works. My choice is generally dictated by the units system for my project (e.g. 0.371 or some other irrational decimal) then I switch to Custom and proceed downward to the next "best fit" rational decimal. If the scale proves awkward for use (e.g. This provides an initial rough scaling that is often good enough with just some slight repositioning of the views. Initially I set the Scale Type to Automatic and click Apply. Thus reducing the clutter of measures around any one view. This means that all but the corner view become 2D and that any view can be used to provide at least one extent measure. I generally set my central/main view to be either the most complex, or most representative face. Above the check boxes, you can set you Perspective View (First or Third angle), the Scale Type (Page, Automatic, or Custom), and if custom was set as the scale type, then you can set the scale for the group as a whole.Īs I do custom joinery, I often have complex "one of" parts, and this multiple linked view method is handy to provide a good set of relational drawings.
FREECAD SCALE SERIES
This begins with the view shown in the model space and allows you to add views from the eight surrounding camera position and from the rear using a series of check boxes. top, front, right, top right 3D, etc.) then you can use the "Insert Multiple Linked Views" button on the Tech Draw workbench. However, if you wish several views of the same item (i.e. If you will be placing multiple different images on the same drawing, then you must change both scale type and scale for each image independently. You can them set any scaling of you choice for that image. To achieve the greatest flexibility of scaling, which is what I believe is your intention, change the scale type to "Custom".
one that cannot be changed after the fact). This however, also leads to a fixed scaling (i.e. If you change to scale type to "Automatic" it will adjust the scale to a size that will allow that image (or linked images group) to fit upon the set paper size. By definition, the only scale for Page is 1. I notice in your screen shots that the parameter "Scale Type" is set to "Page". This works as expected for the other fields in the same section (X and Y), so I assume it is not yet implemented. Changing the value of scale to a number different from 1 doesn't change the scale of the view, even after clicking awayĬhanging the value of rotation to a number different from 0 doesn't change the orientation of the view.
