# Ortho with 45 degrees

## Recommended Posts

I understand about the 45 degree increments but what I don't understand is why he only wants 0, 45 and 90? He has said that several times so I'm assuming he doesn't want 135, 180, 225, 270 and ﻿315. I don't understand ﻿why those other angles are a problem? And I'm not even sure if a custom command will be able to do what he wants because those other angles are automatically generated when you initiate a 45 degree angle snap.

Polar Tracking works great for me, but as you said, if he wants a true lock down of the cursor, he will have to get someone ﻿to help customize that.

True, it is confusing. The user keeps saying "Ortho plus 45°", which is hard to interpret. In my mind I think the user wants ortho angles, then each 45 angle in between. 8 angles total is how I am seeing it.

Yep, that's what I thought too, but every time someone mentions Polar Tracking, the OP says no, he only wants 0, 45 and 90. So yeah, I'm confused. Lol

Yes correct. That's what I'd want. Thank you.

He's just wanting to lock down a 45° incremental angle only with his mouse. Not possible without some type of customization as far as I know.

I'm getting confused with "only 45 and 90 degree angles" because 45° factors into 90°, so the request for 90° is irrelevant I'm assuming? The angles he's wanting locked down, as I see it, are as follows:

• 45°
• 90°
• 135°
• 180°
• 225°
• 270°
• 315°

Polar Tracking can achieve the above, but it sounds like the user wants a true "lock down" of the cursor movement path. If this is all accurate then I do believe a customization would be in place.

Yeah this is exactly what I'd like. I'll have to go to the lisp section for this then.  Thank you very much!

hi I just notice this, for further discussion at AutoCAD customization

example: draw line command

p/s: IMO the reason orthomode  must be  0d-90d due to we must consider Z not just X,Y.

if you customize ortho 45 there would be 2 different results (either XY plane & 45d or Z elevation).

ie: you can write routine but only works in the XY plane.

When I figured out how to use polar/object snap tracking, I dropped ortho like a hot potato and never looked back.
