I only joined the forum over the weekend, having purchased an iMac and TCMac last week. Before disagreeing entirely with 135boom (apologies in advance!) I suppose I'd better outline my background with engineering drawings.
I've been doing engineering drawings for 51 (ouch!) years, and using Turbocad for Windows for the last 20 years, currently V15Pro, so I'm well versed in driving it, 95% of what I do is 2D. Which is just as well, as I'm but one step above rubbish at 3D. I guess that after 50 years of converting 3D objects into 2D drawings, and 2D drawings into 3D objects, my brain is stuck in 2(n)D gear.
Naturally, I have a large collection of TCWin drawings that I need to access. That was the first shock - I had naively assumed it would read TCWin files, but it won't, and when I convert them to .dxf or .dwg and import them TCMac messes up the dimensions (but strangely, only some of them, not all!) and looses some of the line formats.
The User Guide is best described as dysfunctional, so I've spent the whole weekend struggling to get to grips with the program - which is why I joined this Forum. I'm well aware that I'm still at the bottom of the learning curve for TCMac, but nevertheless....
I have the diametrically opposite view to 135boom.The interface for TCMac is very poor compared to TCWin, it doesn't flow for me, and it lacks some (many?) of TCWin's capabilities - or I haven't found them yet! Things like model space and as many paper spaces as one wants, formatting of dimension lines seems to be limited to arrow heads, units formatting is very limited, can't get to an objects properties by left clicking the mouse, haven't found a way of locking a setting (e.g. offset for a parallel line, one has to re-enter the distance every time one does a parallel line, whilst holding down the mouse button), no offset copy, no cancel option on the left button, zooming is very inconvenient (position pointer on item in say top left corner, zoom in to item, it gets bigger but remains in top left corner, whereas TCWin positions the zoomed item in the centre of the screen).... it goes on.
For me, the change to TCMac is approaching disaster level, so it looks like I'll be loading Parallels/Win10/TCWin onto the iMac.
