After you have opened a planning or selected another projection during the planning process, parts of your drawing are no longer visible. There are two possible reasons for this issue.

When planning, you use many dialogs – both free-floating and docked (a non-movable part of the program interface). In the case of free-floating windows, they may disappear for 2 reasons:

Backup files ensure that your plans are not lost should pCon.planner crash.

pCon.planner automatically creates a backup file for your current plan – as long as you haven’t disabled this option in the Program Settings. We recommend leaving the automatic creation of backup files enabled.

The DWG format is a compressed file format. As with a packed file, the file size displayed in your system (e.g. in Windows Explorer) does not occupy the same size as the plan that you edit in pCon.planner. How much memory an opened DWG file uses can vary, and many factors can determined the amount of memory used.

There are several alternatives to relocate the User Coordinate System (UCS) if you want to use it as a means to move objects in relation to a given position in the plan.

When you render images or videos in pCon.planner, you can choose from various default settings called Renderer Profiles.

Select images with a suitable size (for example 2048×2048 pixels).
If you use high-resolution images as textures, set the Texture Quality to Extra High.

The Insert Unit indicates the unit of measure in which objects should be inserted. You can change this by clicking on the Application Menu, choosing Document Properties and switching to the Settings tab. Changes pertain to the current plan.

The correct Insert Unit is important if you are editing plans from other CAD programs.

The Standard Scaling Unit – also known as the Scaling Unit – is necessary when you want to insert objects of an unknown scale. The Length Unit describes the standard when inputting the measure of length. The Insert Unit has an effect when you want to use plans created in another CAD program. Click on the respective unit for more detailed information.

It is likely that you installed the free version of pCon.planner. To check, look at the top (on the title bar) of the program window. There you can read whether the currently-installed edition is pCon.planner (the free version) or pCon.planner PRO (the professional edition). Please bear in mind that a data connection in the free version of pCon.planner is not possible.
