Hi all
I noticed this when designing a house.
If you put a TechDraw View of something the size of a house onto a A3 or A4 page we reach the limit of decimal places able to be entered in the property editor. For example with my file below 14m by 6.3m Part Box, the Automatic zoom gives 0.01 scale factor which is about correct. But if you want to change it you can only double its size by going to 0.02 which is too big. So the issue is that we need smaller numbers i.e. more decimal places, so that we can put even larger items views on the page but also so that we have a much finer control on the actual scale value.

Re: View scale property needs more decimal places
Hello @ wandererfan, While looking into those scales and trying to find a way to work in imperial scaling, @ Yorik had given me this nice trick where you can calculate the scale. And having the decimal units set to 10 as a number of decimal was really helpful.
for example
If I need a drawing on paper sheet to be at 1/8" scale - 1'
the calculation goes as this
1/8" = 1'
1/8" = 12"
0.125" = 12"
Scale = 0.010416667
That's why I had to create a 10 digit decimal in other to accommodate for the best precision possible.
So basically, how to have a list of settings and scales predefined already, and have an extra one which sames "custom" so that one can still have the ability to enter in the scale he needs.
I hope this is not a conversation started on a dedicated thread

Re: View scale property needs more decimal places
Difficult to do in the property editor, but one "good intention" for v0.19 is to have a task dialog for creating/editing view parameters (like Section and ProjectionGroup have now). In such a dialog it would be relatively easy to selection list of standard scales.regis wrote: ↑Sat Dec 08, 2018 4:54 pm That's why I had to create a 10 digit decimal in other to accommodate for the best precision possible.

Oh good idea but how exactly do you mean? do you a screenshot? of the editing parameters like section and projectionGroup..wandererfan wrote: ↑Sat Dec 08, 2018 11:33 pmDifficult to do in the property editor, but one "good intention" for v0.19 is to have a task dialog for creating/editing view parameters (like Section and ProjectionGroup have now).

Haha great I trust your coding magic.wandererfan wrote: ↑Sun Dec 09, 2018 12:25 amJust an idea at this point, nothing to show. It would provide a convenient way of setting Direction, Scale, Rotation, etc.
