I've been using Draftsight for the past few months and have encountered very few problems until this past week..

I am desperately trying to finish some work which contatins filled triangles as the heads for arrows (if there is an arrow shape creator please let me know!)

So my arrows which are horizontal show perfectly on the pdf but the ones that are vertical, pointing up or down, do not show properly at all with just the very middle part of the triangle showing a blurred black blob/oval shape.

I've tried deleting these to draw them again but the problem still occurs..

I have been using these arrows for a while and have never had a problem before so cannot understand why it has suddenly happened on numerous drawings and whatever I do doesnt fix it!

Please note the arrows show perfectly on the model and sheets and I have tried re-installing Draftsight too..

I have just tried to fill a triangle pointing downwards in a brand new sheet and then exporting to pdf where it appears that the fill is only working for a diamond shape, leaving two smaller triangles at the top half of the triangle either side of the diamond completely blank..

If anyone knows of a fix or alternative way to create the arrows that would be greatly appreciated as I really need to get these drawings finished!

Thanks!
