I have used Corel Draw for years and years.
Have tried Adobe Illustrator, YUUUCK!!!
But I have fallen in LOVE with Affinity Designer for MacOS!!!
I use vector illustration software quite a bit in, believe it or not, construction management and estimating.
Never know when I have to create my own plans details, or illustrate an existing condition in the field.
BUT...line/curve arrows are the cornerstone of Designer's purpose in my life, and they're missing!!
From what I can tell, in spite of this frequent and long lived request from many others before me, they've been missing since inception.
Every time I need to make a drawing, I have to fumble around with the arrow shape tool.
Very frustrating.
AFFINITY...PLEASE ADD ARROW HEADS TO LINES/CURVES!!!!!!!!!!!!!!!
While you're at it, dimension lines, with a scaling feature would be a great Christmas present for us this year.
If you take a peak at BluBeam Revu, you will find some great tools for the construction industry.
I'd be willing to pay (a reasonable price, i.e. $20 to $50) for a Designer Construction Add-On pack that will add scalable dimension, area, volume, and perimeter tools.
