If you use Draw -> Insert file, you can import the bitmaps and decide at that point how big they will be by the placement of the corners with the cursor.

CC then asks you for the first corner, and then the second corner. If you have a snap grid turned on you can put them down at any exact size you want.

I don't know if there are any settings you can alter for the result of drag and drop.

Yes. But every last one of those several contours would have to go on it's own sheet.

At a rough count that would be 12 more sheets than current.

The easiest way is probably to pick a single tree symbol and scale it to the size you want all the trees to be (without actually pasting it). Then right click with the tree still on your crosshairs and note the scale you are at. Here, below the scale is 0.2.

Then click Finished and go to the Drawing Properties button and set the scale in the Drawing Presets that it opens to be the same as the scale of the single tree.

Then, delete the forest you've just drawn and redraw it. The new default symbol scale will cause the trees used by the tool to be rescaled to the size you want them to be.

In this test map below I set the default symbol scale to be 0.5 instead of 1, then drew a new patch of forest on the left. The existing patches of forest on the right remain at the original default scale that was set when they were pasted (1). That is why you need to delete and redraw the existing forests that are the wrong scale.

Since you already own the older versions it might be an idea to contact Profantasy and ask if there is any upgrade price. Since I wasn't around when they were upgraded I don't know if there were or were not.

Try the 'General Manager' on the Contacts page. That's Ralf. He will know if there was any reduced price upgrade and if it still applies.

EDIT: He might be a couple of days getting back to you, though, since he's currently at Gen Con.

CC3 and CC3+ are completely separate.

A fresh download is always better than an old installer.

When you've downloaded everything start by installing CC3+, the latest CC3+ update, then the main add ons (DD3, CD3 etc), and then the rest in no particular order. Finish up by re-running the latest CC3+ update.

If an installer is set to open CC3+ at the end of it's run by default, let it do so, but close it down again before running the next installer. Never run an installer while CC3+ is open.

Shout if you have any issues.

EDIT: a bit more clarity on the difference between CC3 and CC3+. CC3 is now obsolete and no longer supported. Most of the add ons will no longer work with it, having been updated to work with CC3+
