First go with SCARM

You need to do an export as BMP or JPG (I forget which SCARM does.), then you can add it to the body of your post.  Only the SCARM software can read the file and make sense of it.

SCARM supports both BMP and JPG. After you export the design, remember where you saved it and select "Add Attachments", the same as you did to attach the .scarm file. Navigate to the image file you saved and Open it. This will upload the file and then check the box that says to "Insert all images and videos in post body" when it appears. Here's the JPG:

Thanks for the advice. Will practice.

Not bad for the first pass. Windows also has a handy tool called a snip tool. I pin it to the task bar. drag it around whatever is on the screen, save and name it.

I have attached the FastTrack lengths chart to assist you in actual track fitment.

Fit your straights and added operating tracks
