Workpack: Unit Systems

What is ‘Unit Systems’ feature

• Workpack allows to change system of measurement units between imperial (inches, feet and miles) and metric systems (centimeters, meters and kilometers):

Before the switch:

 

After the switch:

Three Levels of Unit System Settings

Account:

• To change the global setting, go to the top right corner of Dashboard screed, click on your email and then on Profile item:

  

• You will open Info & Setting screen where you can select a unit system item you want to set up. Don’t forget to click Save button:

  

• Default item is imperial units

• Unit system change on account level affects according settings of new projects only. Unit system settings of existing projects will continue to stay unchanged

• Unit system change on account level affects the default unit system setting only for new documents. Unit system settings of existing documents will continue to stay unchanged

Project:

• On project level, unit system can be chosen at project creation and can be changed for existing projects

• To change unit system of an existing project, click the edit icon of the project in dashboard screen:

  

• Select the item you want. Please note that unit system change will affect only new documents of the project:

  

• Add project screen looks the same as edit one but without the bottom notice since all the documents here will be new:

  

• Default unit system for new projects is defined by an according account setting (see above). If the account setting was not touched, default will be imperial units.

Document:

• To switch unit system, click on the ham menu in the top right corner of the app, then click on Measurement Units menu item:

  

• Select dialog opens up:

  

• Default item is defined by account and project settings, their default item is ‘Imperial’

• User can change measurement system at any time: at start, in the middle of the work, and at the end. All values in UI get recalculated right on confirmation of this dialog

Unit Systems Throughout the Document

Scales:

Scale in imperial units: 

Scale in metric units:

• Scales dropdown in metric system looks the same but with metric notation 1 : N:

• Scales between two systems correspond to each other but not exactly. Here’s the chart of accordance:

  Imperial	Imperial to Metric exact	Metric closest
  3''=1'	1:4	1:5
  3/2''=1'	1:8	1:10
  1''=1'	1:12	1:10
  3/4''=1'	1:16	1:15
  3/5''=1'	1:20	1:15
  1/2''=1'	1:24	1:25
  3/8''=1'	1:32	1:25
  3/10''=1'	1:40	1:50
  1/4''=1'	1:48	1:50
  3/16''=1'	1:64	1:75
  1/8''=1'	1:96	1:100
  3/32''=1'	1:128	1:125
  1/16''=1'	1:192	1:200
  3/64''=1'	1:256	1:200
  1/32''=1'	1:384	1:400
  1/64''=1'	1:768	1:750

• For example, we have 3/2’’=1’-0’’ before the setting switch. After switch, it will become 1:75, however, the exact value is 1:64. So, all measurement values will become 17% greater on change than they were in imperial units. To preserve the values, need to set a custom scale 1:64:

  

• Assigned custom scales won’t be changed on the setting change, e. g. ‘1 in = 14 ft’ will become 1:14. However, this is wrong (should be 1:168) and will be fixed in the following updates:

Left Panel:

• Items in the Left Panel show measurement values for group and object items, all according to the type: Walls and Linear Measurements here show length, Rooms and other Areas show areas of polygons

• On the setting switch, measurement values will recalculate from meters or square meters to the feet or square feet and backwards according to the changed scale
