I have a license for LWCAD 4, having upgraded it from my original purchase of LWCAD 2.5 or earlier. Is there an upgrade to the current version from v4 available for purchase?

Thank you!

Is this the wrong place to ask?

No it is good place to ask, but if you have some urgent question, then support is faster.

Because of current significant discount, minimum upgrade license is LWCAD 5.

Currently LWCAD 2018(2020) FULL version is 50% discount from original price, which is less than previous regular update from ver. 4.

Thank you, Viktor! I see that now...!

One question though---Is LWCAD 2018 compatible with LightWave 2020?

Yes it is, and LWCAD 2020 will be released very son anyway!
